Kinematic Hardening Model for Pipeline‐Soil Interaction under Various Loading Conditions

Abstract

A kinematic hardening two‐surface model of soil‐footing interaction for pipelines under various loading conditions is presented. The model requires 13 parameters. Most of these parameters can be derived directly from a set of model tests or from conventional soil mechanics theory. Model performance is demonstrated through modeling the drained behavior of pipeline‐soil interaction under typical loading conditions. Predictions from the model compare well with experimental data obtained in a series of loading tests on shallowly embedded pipelines. The model provides an efficient and direct way to evaluate the behavior of a pipeline under various loading conditions.
