چكيده فارسي :
Analysis and design of buried pipelines are complicated problems. The reason lies in the fact that it
incorporates interaction between soil and pipeline as well as nonlinear behaviour of surrounding soil. In the
present study, the effect of soil elastic and plastic characteristics on mechanical behaviour of pipeline is
investigated numerically. Strike-slip fault displacement is imposed in various angles to longitudinal pipeline
axis. Soil is considered as an elastic-perfectly plastic material conforming Mohr-Coulomb criterion. The
results obtained numerically were compared to well-known analytical methods. Although, analytical
methods and numerical softwares prepares loads of possibilities to take into consideration pipe and soil
interaction more realistically, the present study shows that a comprehensive experimental study should be
done in each of the cases to calibrate and determine realistic values for soil and pipe interaction needed for
various methods.
