      <title>GROUND MOVEMENTS CAUSED BY DEEP TRENCH CONSTRUCTION</title>
      <link>https://trid.trb.org/View/186066</link>
      <description><![CDATA[A significant proportion of sewer renewal, replacement and new construction involves deep trenching and tunnelling works in urban areas.  The lack of information on the ground movements produced by trenching makes it difficult to reliably assess the effect on adjacent roads, buildings and buried services.  Two full-scale trenching trials in London clay at Bracknell and in compressible alluvium at Avonmouth are described.  Information is provided on the effect of the component activities of the trenching operations on the ground movements which develop in the short and longer term, and on the pattern of surface and subsurface movements.  The response of an instrumented cast iron pipeline buried at shallow depth parallel to the line of the trench at the Avonmouth site is also reported. (TRRL)]]></description>

      <title>RESPONSE OF A PIPELINE TO GROUND MOVEMENTS CAUSED BY TRENCHING IN COMPRESSIBLE ALLUVIUM</title>
      <link>https://trid.trb.org/View/181250</link>
      <description><![CDATA[Disturbance of the ground due to work on buried services, such as the renewal, replacement or new construction of deep sewers, is likely to cause differential ground movements in the vicinity.  This may be a factor contributing to failure in nearby service pipelines such as drainage, gas and water mains.  This report describes the response of an instrumented shallow buried pipeline to ground movements caused by adjacent deep trenching in a compressible alluvium.  The small diameter cast-iron pipeline was installed at a depth of 0.75M some two and a half months in advance of the deep trench excavation.  It was located parallel to the projected deep trench and 2.25M from one face.  Only small changes in bending strain and pipe deflection occurred both during pipe installation and subsequently during excavation of the deep trench.  Larger increases in strain and pipe deflection were measured due to settlement during backfilling.  On completion of backfilling some reduction in strain levels was observed, although relatively large permanent bending strains remained in the sections of the pipeline adjacent to the ends of the trench. Good correlation was obtained between the movement of the pipeline evaluated from strain measurements using a semi-graphical integration technique and that actually recorded.
