The Effect of Seismic Waves on Buried Gas pipelines

In this paper, the behaviour of buried pipelines under
the effect of propagation of seismic waves and faulting is
studied seperately.
The stability of this type of structure was first studied
by using three different methods proposed by
Newmark-Hall, kenndey et al. and Wang - Yeh under the
effect of ground faulting. By parametric study, the effect
of soil types, size of pipeline, depth of embedment, the
incident angle of fault with pipline, the type of fault, the
supporting conditions of the pipeline in the vicinity of the
fault are analyzed and some technical recommendation
are presented.
Finally, by using a lumped model for the pipeline
structure, it is analyzed by using, the step-by-step method
of Wilson - ?. The effect of the most important
parameters on the pipeline are mentioned and based on
the implemented analysis, some applicable rules are recommended.
