采用 Ansys 有限元计算软件，选取某抗滑桩加固滑坡为例，采用人工地震波，研究地震作用下抗滑桩与坡体相互作用机制。研究结果表明：各特征点动土压力、动位移值均随着输入地震波加速度的增加而增加，其峰值出现时间稍晚于地震波加速度峰值时间。处于稳定岩体部分桩的反力最大值和分布形式因不同时刻的地震加速度不同有较大的差异。滑体内部段桩土压力在深度上的分布除桩顶以外，其余部分的土压力基本属于均匀分布。输入的地震波加速度越大抗滑桩的变形越大，桩身位移沿桩顶向下减小。

The FEM software ANSYS was adopted to study on the interaction between slope and stabilizing pile under seism loading, by a case of landslide reinforced by a stabilizing pile, and an artificial earthquake was excited as input motion. The results indicated as follows: Dynamic soil pressure and dynamic displacement at characteristic points of stabilizing pile were increased with the increase of acceleration of earthquake motion. The appearance time of their peak values was later than that of the peak of earthquake acceleration. There were larger differences occurring in the maximum value of resistances on the partial pile lain in stable rockmass and resistance distribution forms with different accelerations in different times. The distribution of the soil pressure on the pile inside the landslide was homogeneous except the top of the pile. The greater the earthquake acceleration, the larger the deformation of the anti-slide pile. And the displacements of the pile were decreased from top to bottom.
