摘　　要：在地震作用影响下 ,墙后填土处于极限平衡状态时 ,假定破裂面为一条通过墙趾的旋轮线。从墙后土楔中取出一微薄水平层 ,研究其在水平惯性力下的平衡 。The simulating static method is discussed for obtaining the seismic active earth pressure of retaining wall. The premise of this method is that the surface of rupture is a cycloid via the foot of retaining wall. Then a very thin horizontal layer of the fill behind retaining wall is analyzed. The balance equation is deduced by considering the horizontal inertia force. The calculating results are in good agreement with the experimental results. 
