      <title>Konfliktfeld Untertagebau und alpine Wasserressourcen. Konsequenzen fuer Planung und Bauausfuehrung / Potential conflicts between underground construction and Alpine water resource</title>
      <link>https://trid.trb.org/View/945476</link>
      <description><![CDATA[Der Trassenverlauf der Eisenbahnachse Brenner-Zulaufstrecke Nord im Unterinntal ist das Ergebnis einer intensiven planerischen Auseinandersetzung mit den UVP-relevanten Schutzguetern und den technisch-wirtschaftlichen Erfordernissen einer Hochleistungsstrecke. Ueber 80 Prozent der rund 40 km langen Trasse verlaufen unter Tage, wobei dem Schutzgut Wasser ab Planungsbeginn projektstrategische Bedeutung beigemessen wurde. Konflikte zwischen den geotechnisch-bautechnischen Anliegen und Erfordernissen des Untertagebaus einerseits und der Wasserwirtschaft andererseits liegen in der Natur der Sache, wobei projektphasenabhaengig unterschiedliche Themen dominieren koennen: - Erkundungsstrategie sowie Umfang und methodischer Tiefgang der wasserwirtschaftlichen Beweissicherung im Rahmen der hydrogeologischen (Vor-)Untersuchungen. - Prognosesicherheit in der Beurteilung der Auswirkungen der Baumassnahme auf den Wasserhaushalt in Abhaengigkeit vom Erkundungstiefgang in den unterschiedlichen Projektphasen. - Baukonzepte, insbesondere Draenage- und Abdichtungskonzepte fuer die Bau- und Betriebsphase in Abhaengigkeit vom Aquifertyp und dem Druckniveau des Grundwassers. - Emissionsbelastungen im Rahmen der Ausleitung von Tunnel(ab)waessern sowie abfallwirtschaftliche Aspekte in der Bauphase. Konfliktvermeidung und offensive Konfliktbewaeltigung ermoeglichten den Abschluss der Umweltvertraeglichkeitspruefung (UVP) mit dem Umweltvertraeglichkeitsgutachten plangemaess im Jahr 1999. Die eisenbahnrechtliche Baugenehmigungsverhandlung wurde im Herbst 2001 positiv abgewickelt, und fuer Ende 2002 ist der Beginn der Hauptbauarbeiten geplant. (A) ABSTRACT IN ENGLISH: The alignment of the Brenner railway axis - Northern feeder line in the Lower Inn Valley - is the result of intense design analyses involving both the natural resources to be protected which are of relevance to the environmental impact assessment and the techno-economic requirements of a high-speed railway line. With more than 80 percent of the approximately 40-km-long railway line running underground, water was, from the very beginning of the design phase, recognized to be a sensitive good of strategic importance for the project. Conflicts between the constructional and geotechnical needs and requirements of underground construction on the one hand and of alpine water resource management on the other hand lie in the nature of such projects. The predominant issues may, however, change depending on the individual project phases: - Exploration strategy as well as extent and methodology of the hydrological status-quo documentation performed in the course of the hydrogeological (pre-)investigation. - Accuracy achieved in assessing the impact of the construction measures on the water resources, depending on the exploration level in the respective project phase. - Construction concepts, especially drainage and waterproofing concepts for the construction and operating phase, depending on the type of aquifer and the groundwater pressure level. - Emission loads resulting from the discharge of tunnel drainage water and wastewater as well as waste management considerations during construction. Conflict prevention and pro-active conflict resolution permitted the environmental impact assessment to be completed in 1999 as scheduled. The permit application procedure in line with railway law was successfully finished in autumn 2001 and the main construction works are planned to commence by the end of 2002. (A)]]></description>

      <title>Erkundungsschacht Paierdorf - Baugrunderkundung und geotechnische Parameter</title>
      <link>https://trid.trb.org/View/944116</link>
      <description><![CDATA[Im Zuge der weiterfuehrenden Erkundung fuer den Koralmtunnel der geplanten Eisenbahnhochleistungsstrecke Graz-Klagenfurt wurde fuer die Planung des etwa 121,5 m tiefen Erkundungsschachts Paierdorf ein Baugrunduntersuchungsprogramm ausgefuehrt. Im Bereich des Schachtbauwerks wird der Baugrund ausschliesslich von Lockergesteinen sowie von gering zementierten Sedimentgesteinen mit sehr geringen Gesteins- beziehungsweise Gebirgsfestigkeiten aufgebaut. Die Charakterisierung der angetroffenen Locker- und Festgesteinstypen erfolgte in Anlehnung an die Richtlinie fuer die Geomechanische Planung von Untertagebauarbeiten mit zyklischem Vortrieb. Fuer jede der identifizierten Gebirgsarten wurden geotechnische Parameter als Grundlage fuer die Ermittlung des Gebirgsverhaltens sowie fuer die Bauwerksplanung festgelegt. Aufgrund des dominierenden Einflusses des Bergwassers auf das Gebirgsverhalten wurde fuer die Planung das Gebirgsverhalten unter Beruecksichtigung einer systematisch durchgefuehrten Grundwasserabsenkung ermittelt. (A) ABSTRACT IN ENGLISH: The Paierdorf Exploratory Shaft, which is designed with a depth of approximately 121.5 metres, is part of the Continuative Investigation Programme for the High-Performance Railway line between Graz and Klagenfurt. At the shaft location the ground is built up by soil and poorly cemented sedimentary rock types with low to very low strength properties. The characterization of the encountered soil and rock types was performed, following the guideline for the "Geomechanical Design of Underground Structures with Conventional Excavation". For each of the identified rock mass types a set of geotechnical parameters was assigned for the assessment of the rock mass behaviour as well as for the design of the shaft. Because of the dominant influence of the groundwater on the rock mass behaviour for the design the rock mass behaviour was determined under consideration of a systematically applied groundwater lowering programme.

      <title>Asbestos Isolation</title>
      <link>https://trid.trb.org/View/890279</link>
      <description><![CDATA[The Cesana tunnel, located in the Piedmont area of northwestern Italy, presented the first instance of a tunnel having to be excavated through asbestos-bearing rock in Italy. The excavation method and containment system had to protect the health of the workers while tunneling and handling muck. Additionally, a site was needed for storing the hazardous muck. The asbestos-bearing rock caused tunneling to be suspended along a 105-meter stretch. An underground site was built to store the muck, marking the creation of the first underground hazardous waste storage in Italy. Additionally, an environmental impact study of the tunnel stretch where the asbestos is located was also required. The pre-tunneling exploration was limited due to mountainous terrain above-ground. The tunnel was expected to pass through an entirely dolomite type of formation. Once the presence of asbestos was determined through electron microscope scans and a microanalysis of dispersion energy, the method for removing and storing the muck underground was decided upon. The solution that was chosen uses pre-cast concrete containers that can be sealed and easily transported and stacked in the vault prepared for their storage. The design and siting of the storage area is discussed, including the geological evaluation of the location, the geo-mechanical evaluation and other evaluations. With all authorizations in place, construction is expected to begin in the summer of 2009.]]></description>

      <title>Geological mapping of regional structural lineaments for tunnel construction</title>
      <link>https://trid.trb.org/View/768536</link>
      <description><![CDATA[The Hakkoda tunnel is part of the Tohoku Shinkansen, which is under construction. The tunnel is about 40 m deep in the Yakata area. According to former geological data, the tunnel will pass through a regional structural lineament in the base rocks, which are highly fractured and faulted. There is a small river above the tunnel in the area, which provides drinking water for downstream villagers. Due to the low permeability and the mud rocks, shown at the nearby outcrops because of geopressure during the construction of other sections. This can be a potential danger for the tunnel construction at this particular site since river water can potentially leak into the tunnel through the fractures or faults during the construction. There is also a water dam in the neighborhood. There is a possibility of damaging the dam during the construction of the tunnel in this complicated geological environment. For safety reason, it is important to map the geological and hydrological settings in detail before construction. Considering the accuracy of various geological or geophysical methods and their applicability in the region, we employed four geological survey methods. A comprehensive work plan for the tunnel construction was made based on the results. Four geological prospecting methods were employed sequentially during the survey. They are: (1) Electrical Sounding, which was used to map the geological structure, positions of faults or fracture zone and possible water layers in the region. (2) Vertical drilling, which provided more detailed mapping of the geological settings and physical properties of the rocks. (3) Surface wave exploration and Microtremor measurements. Both methods provide more detailed mapping for the regional structural settings, faults or fractured zones. The methods also have much a better three-dimensional resolution in comparison with the electrical method. (4) Horizontal drilling from the work face to obtain more detailed information on properties of the rocks and fractures or faults ahead of the tunnel under building. Water samples were taken from these horizontal wells to evaluate the possibility of possible water invasion by comparing and analyzing the quality of various waters. Correctly integrating various geophysical and geological data was the key to the success of detailed geological mapping in the area, from which a comprehensive work plan was made. The survey results were also accessed by comparing the geological predictions with what we saw at the work face during the construction. In the complex geological environment like this, it is essential to utilize various geological and geophysical methods in order to correctly predict the geological conditions in advance. An optimized working plan can be made based on the detailed geological mappings. Even for areas or zones with the high possibility of water leakage, a proper supplementary work at small scale will be able to prevent the water leakage without injecting cements into the base rock at a much larger scale. This optimized working plan will potentially reduce the construction cost. In conclusion, considering the construction cost and time, favorable geological and geophysical methods were selected based on known geological information and regional geology in the area. The tunnel construction work plan was optimized by correctly integrating various geological and geophysical results. (A). "Reprinted with permission from Elsevier".

      <title>EARTHWORKS - DRAINAGE - SUBGRADE. REPORT FROM AUSTRALIA --PIARC XVIII WORLD ROAD CONGRESS, BRUSSELS, BELGIUM, SEPTEMBER 13-19, 1987</title>
      <link>https://trid.trb.org/View/296558</link>
      <description><![CDATA[Over the last three years in Australia there has been a marked increase in road construction by contract.  This has necessitated more detailed geotechnical investigations and reporting.  This report describes new equipment and techniques used and investigated, such as use of the piezo-cone penetrometer, electromagnetic methods for sub surface exploration and applications of remote sensing.  The use of geotextiles in slip restoration and for maintenance of constant moisture conditions in embankment is described. A number of batter stability problems including the effect of internal stress release in a massive rock cutting were encountered.  Methods of alleviating rock face problems are described together with environmental protection measures employed at sensitive locations.  The new Australian road research board publication "some aspects of subsurface drainage design construction and maintenance" is introduced with 2 new types of subsurface drains to suit construction methods.  Examples are given of the use of non-traditional materials as well as of a monitored length of temporary pavement which illustrates the degradation of the quality of lime stabilization with time.  For the covering abstracts of the congress see IRRD 812115 and 812116.]]></description>

      <title>COMBINATION PROBE - A NEW INSTRUMENT FOR SUBSURFACE EXPLORATION</title>
      <link>https://trid.trb.org/View/211527</link>
      <description><![CDATA[As part of its highway transportation research program, the Federal Highway Administration (FHWA) has investigated tunneling technology extensively to reduce the engineering risks, and therefore the costs, associated with highway tunnel construction.  Experience has shown that attempts to reduce engineering costs by minimizing investigation of a proposed tunnel site often are counterproductive. Misjudging underground structure may result in selecting the wrong tunnel excavation technique or under- or overdesigning the tunnel supports.  Present methods for obtaining pertinent information for the design and construction of a highway tunnel include assembling geophysical and geotechnical information from other nearby projects.  The combination probe system promises to be a powerful tool for reducing tunnel constructions costs by interpreting the geophysical data of the given tunnel site.]]></description>

      <description><![CDATA[This report presents the results of a field evaluation of advanced methods of subsurface exploration on an ongoing urban rapid transit tunneling project. The objective of this study is to evaluate, through a field demonstration project, the feasibility, applicability, reliability, and cost effectiveness of selected advanced methods of subsurface exploration and instrumentation to produce data usable for rapid transit tunnel design and construction within the time, cost, and schedule constraints common to the industry. Numerous methods of subsurface exploration, including hole advancement techniques, sampling procedures, and geophysical logging tools, were used to predict stratigraphy within a test section on an urban rapid transit project under construction. A test section on the Massachusetts Bay Transportation Authority Red Line Extension-Northwest, Cambridge, Massachusetts, was selected to evaluate methods of subsurface exploration used to investigate stratigraphy, ground water levels, bedrock structure, and other geotechnical parameters. The site represents a typical urban setting with the test section located under a major, four-lane divided street, with structures adjacent on both sides.]]></description>
