The buried pipeline is divided from the earth medium together with the soil around, and the calculated area including the pipeline and the soil is established. The pipe is regarded as the space structure, and modeled by the four nodes thin-shell elements, while the soil solid elements. The 3-D nonlinear contact elements are used to simulate the slip and isolation phenomena between the pipe and the soil. The initial stress state in the pipeline-soil system is also estimated for response analysis. The nonlinear seismic responses of buried pipelines and surrounding soil under permanent ground deformation are analyzed using pseudo-static analysis method without considering the fracture of the soil. Some influential factors, such as crossing angle, soil displacement, ratio of diameter and wall-thickness, friction coefficient and buried depth are researched, and some regular conclusions are drawn.
