STATIC AND DYNAMIC LOADING TESTS ON SHALLOW-BURIED FLEXIBLE PIPES

The article describes tests carried out at the Transport and Road Research Laboratory (TRRL). Pipe deflections, wall strains and soil pressures are measured and used to assess structural performance of the pipes under dynamic and static loadings applied to shallow buried pipes installed in different beddings with different degrees of compression. The methods of loading and instrumentation are described. The results show the critical importance of the standard of workmanship during installation. Low quality materials placed to a high standard of workmanship have produced the same results as high quality materials placed with a low standard of workmanship. It is concluded that more effort should be made during design to make a realistic assessment of the standard of workmanship likely to be achieved during construction. The Boursinesy theory provides a useful basis for estimating the traffic loading on buried flexible pipelines. /TRRL/
