Numerical Simulation of Soil-Pipeline Interaction in a Ground Subsidence Zoneby A. P. S. Selvadurai, Carleton Univ, Dep of Civil, Engineering, Ottawa, Ont, Canada,
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.
