Numerical Simulation of Soil-Pipeline Interaction in a Ground Subsidence Zone

by A. P. S. Selvadurai, Carleton Univ, Dep of Civil, Engineering, Ottawa, Ont, Canada,



Document Type: Proceeding Paper

Part of: Advances in Underground Pipeline Engineering

Abstract:

In this paper, the flexural interaction between a buried pipeline and the surrounding soil is examined by employing a combined boundary element-finite element scheme. The flexural interaction occurs at a ground subsidence transition location. The numerical results presented in the paper illustrate the manner in which the flexural deflections and flexural moments in the transition zone are influenced by the location of the buried pipeline and the relative rigidity of the pipeline-soil system.
