采用 Ansys 有限元计算软件，以某滑坡体为例，建立了有限元的三维模型，并选取 Kobe 地震波中的代表性波段，研究了在地震作用下抗滑桩的侧面应力、动土压力以及桩身的弯矩分布规律。结果表明：在地震作用下，抗滑桩侧面受到不可忽略的侧面应力，对其抗震能力产生有利影响；地震时，抗滑桩产生的弯矩呈现/凸0形，在滑坡带部位达到最大；同时还出现负弯矩，对抗滑桩的抗震不利，在设计时应加以考虑。

The finite element calculation soft ware Ansys w as used to develop a three-dimensional model of a landslide. The repre-sentative range of Kobe earthquake wave was select ed to investigate the dist ribution characteristics of lateral stress, soil pres-sure, and bending moment of the ant i-slide pile. The results show ed that the lateral st ress of the anti-slide pile is significant un-der earthquakes, w hich may have a favorable impact on the anti-seismic performance of the pile; the bending moment of the anti-slide pile show s in the / convex0 shape and it reaches the maximum in the landslide area during the earthquake; and the occur-rence of negat ive moment can have an adverse im pact on the ant i-seismic performance of the pile.
