Sand liquefaction has induced many damages to the buildings. However,few studies have been done to investigate the seismic response of subway underground structure buried in liquefiable soil foundation,especially when it is buried in liquefiable soil foundation with the ground surface slight inclined. Accordingly,the shear deformation of liquefied sand was modeled by a special soil constructive model and the Arbitrary Lagrange-Euler method used to prevent the distorted soil elements. As a result,a soil-underground structure interaction model was made by finite element method. Based on the results,how the inclined angle affect the liquefaction condition of soil foundation,the lateral deformation and floating of subway underground structure,the seismic stress response of underground structure,were analyzed. The seismic responses rule of subway underground station buried in liquefiable soil foundation with the ground surface slight inclined was revealed.
