Numerical Study of Pipe-Soil Interaction Subjected to Strike-Slip Faulting
An important challenge in analysis and design of buried pipeline against the earthquake effects is how to model soil-pipeline interaction. In 2009, Abdoun and his colleagues presented results of tests on buried polyethylene pipelines subjected to strike-slip faulting. The results showed that, for a small ratio of H/D, maximum lateral force of pipe has a good agreement with ASCE relationships; but, a large ratio of H/D is 3 times smaller than ASCE specifications. In this study, after verifying numerical results, the effects of soil parameters on the pipe axial and bending strain were investigated by sensitivity analyses. Finally, it is shown that centrifuge test results for large ratio of H/D are not only reliable and ASCE relationships are very over-estimated for this case, but also the pipe wall thickness has a significant contribution to the pipe soil interaction, whereas it is neglected in ASCE relationships.
