Abstract: 

Pipe-Soil interaction presents a challenging problem of analysis and design of buried pipelines. Even though the accuracy of ASCE relations for calculating pipe-soil interaction is good in certain cases as a number of researchers have demonstrated those relations are rather inaccurate for other cases such as under fault movement. This research evaluates the interaction between sandy soil and polyethylene pipes subjected to strike-slip faulting using a non-linear finite element numerical model. Upon verification of the results of the numerical model using previously conducted experiments, several numerical studies analyses were carried out for pipes with different diameters, thicknesses and burial depths. The results suggest that the pipe thickness and the fault-pipe angle affect the pipe-soil interaction.
Such effects are not reflected in the ASCE relations considerably. Finally, based on the results obtained, the ASCE relation for the transverse-horizontal interaction between sandy soil and polyethylene pipes subjected to strike-slip faulting was modified.
