This study aims to clarify the development of pipeline buckling during thrust faulting. Based on the coupled discrete element method (DEM) and finite difference method (FDM), the sandbox modeling shows that the cross-sectional flattening coefficient and strain increment distribution can quantitatively identify the geometry and location of the buckled pipeline, respectively. The influence of pipeline existence on the ground surface deformation was also investigated.
