      <title>Geotechnical aspects of prestressed ground anchors</title>
      <link>https://trid.trb.org/View/1192437</link>
      <description><![CDATA[This paper initially defines the types of prestressed ground anchors considered and gives examples of their application.  Planning of a geotechnical investigation is discussed with emphasis on those aspects of particular importance to anchors.  Design approaches for calculating single anchor resistance in rock, cohesionless and cohesive soils are given for the most common types used.  The final section illustrates the interaction of anchor and structure by consideration of the simple problems of providing uplift resistance in rock, and support of a retaining wall in soil (a).]]></description>

      <title>Installation of prestressed ground anchors</title>
      <link>https://trid.trb.org/View/1192436</link>
      <description><![CDATA[Regardless of the thoroughness applied to the design of a ground anchor system the performance of the system depends on the successful installation and tensioning of each ground anchor.  This paper outlines the anchor construction techniques related to drilling in different soil and rock conditions, tendon preparation, water testing and waterproofing, grouting and stressing.]]></description>

      <title>The construction of bored piles</title>
      <link>https://trid.trb.org/View/1192435</link>
      <description><![CDATA[A few of the more commonly installed bored pile types are listed and the current methods of installation of these are reviewed.  Reference is made to the authors own experience in this regard and in some instances suggestions are made for modification of certain practices and specification requirements. Some potential problems which may arise as the result of possible limitations of the constructor and/or the equipment being used are discussed (a).]]></description>

      <title>Bored piles in rock</title>
      <link>https://trid.trb.org/View/1192434</link>
      <description><![CDATA[The conventional methods of constructing bored piles socketed into rock are critically examined.  Rock socket designs normally involve construction related assumptions regarding (i) the conditions of the socket walls and bases and (ii) concrete integrity.  Often these assumptions are not valid in practice, so that better construction equipment and methods are needed (a).]]></description>

      <description><![CDATA[Recent developments in instrumentation and computer facilities have enabled engineers to use dynamic pile testing for accurate predictions of pile load capacity.  A brief background and a summary of the road construction authority's use of such testing is presented (a).]]></description>

      <title>Developments in the concept of compression tube anchors</title>
      <link>https://trid.trb.org/View/1188993</link>
      <description><![CDATA[This paper outlines the concept of compression tube anchorages and reports on the recent developments in the design and application of this new technique used in rock anchoring.  In this system the transmission of the force from the tendon into the rock is achieved by means of a thick walled tube brought into compression by the end of the tendon.  The mechanism of bond of an embedded tube subjected to compression is described and some examples of the industrial application of the anchorages are reviewed.  Results of the laboratory test on compression tube anchors are shown in this paper and some factors influencing the design and reliability of this type of anchorage are discussed (a).]]></description>

      <title>Prediction of footing settlements on sand</title>
      <link>https://trid.trb.org/View/1188393</link>
      <description><![CDATA[The prediction of settlements for footings resting on sands always involves the use of empirical methods and the complexity of a method is no measure of its accuracy.  In this method the relative density of a sand deposit is established empirically from the results of a standard penetration test (spt) and then, using empirical stress strain relationships for sands of various densities, the strains below a footing are predicted and integrated to give the total settlement of the footing. The only field data required in the method are the spt results down the profile, though other means of establishing the relative density of the sand deposit would be equally satisfactory.  The method has been checked with the use of load settlement data extracted from 94 published case histories.  In 50 per cent of the cases the ratio of estimated to observed settlement lies between 0.67 And 1.5, While in 73 per cent of the cases the ratio lies between 0.5 And 2.0.]]></description>
