| Abstract: | By using ANSYS as the software of finite element analysis, a model is set up for calculating finite element of pile foundation with lateral load. Considering the nonlinear relation between pile and soil which jointly operate, the authors simulate lateral displacement of soil mass in pile foundation of laterally extending liquefaction by exerting pressure on soil spring unit to cause its lateral displacement; and carry ont nonlinear finite element analysis of the pile in foundation of laterally extending liquefaction. The reckoning rationally inteprets the extensive ground displacement induced by seismic liquefaction; and the actual seismic damage as shown by the destruction of pile foundation. |

| Keywords: | seismic liquefaction large ground displacement lateral extension or lateral spread pile foundation |
