Numerical simulation of surface soil rupture pattern
The main cause of structural damage in civil engineering across faults is ground rupture resulting from fault activity.In recent years,considerable attention has been given to the study of surface damage caused by fault rupture.However,most of the research has focused on dip-slip faults,with limited reports on strik-slip faults,tensile faults,and compressional faults.There-fore,numerical simulations were conducted using the finite element method to investigate the surface morphology of three types of fault ruptures.The study focused on the influences of fac-tors such as the fault dip angle,soil layer thickness,and key engineering parameters,including longitudinal surface deformation,the width and location of the surface deformation zone,surface offset,and the width and height of the surface uplift.Results indicate that as the fault dip angle decreases,the surface deformation zone moves closer to the hanging wall,and the width and height of the uplifted zone increase accordingly.The distribution of fault surface offset is influ-enced by the modeling boundary conditions,with larger values at the edges and smaller values at the center.Additionally,the study summarized the impact of soil layer thickness on the relevant parameters.
