A numerical model of buried pipeline-soil system subject to reverse-fault is developed, which is used in discontinuous deformation analysis (DDA) coupled with the finite element method (FEM). The pipe is regarded as plane structure and modeled by beam elements, while the soil is discredited into two-dimensional plane strain elements according to FEM. The contact status of discontinuous media is described by the contact analysis of DDA. The initial stress state of the pipe-soil system is also estimated for response analysis. The mechanical responses of buried pipeline and the discontinuous contact analysis between buried pipeline and surrounding soil are analyzed using pseudo-static analysis method without considering soil fracture. Some regular conclusions are drawn. The results verify the feasibility and effectiveness of using DDA coupled with FEM to study buried pipeline. The study provides a new approach and technique for studying pipe-soil discontinuous medium interaction.
