Imposed Ground Strain and Buried Pipelines
TLDR
In this paper, a beam-on-elastic foundation approach was used for the analysis of buried pipelines subjected to longitudinal soil strain resulting from earthquakes or man-made underground explosions, and the effects of this soil strain on the axial strain in the pipeline and relative displacement at the pipeline joints were determined using a beam on elastic foundation approach.Abstract:
A technique for the analysis of buried pipelines subjected to longitudinal soil strain resulting from earthquakes or manmade underground explosions is presented. The effects of this soil strain on the axial strain in the pipeline as well as relative displacement at the pipeline joints are determined using a beam on elastic foundation approach. The pipeline is assumed to be straight and of prismatic cross section. The pipeline, pipeline joints and surrounding soil are assumed to behave as linear elastic materials. Non-dimensional curves are presented relating pipeline strains and relative joint displacement to the relative stiffness of the soil, joint and pipeline.read more

Estimation of dynamic strains in finite end-constrained pipes in seismic areas
TL;DR: The work presents an analysis of the dynamical response of a buried pipe under seismic excitation and concludes that end-constrained finite length pipelines are subject to strains greater than infinite length pipes, or free-end finite length pipes.
