摘　　要：本文介绍了P.Gussmann提出的滑移单元(KEM)法,就档土结构的侧土压力问题给出了一些计算实例。该方法采用有限单元离散化,利用最优化过程求得最佳上限解。该方法可用于土和松散岩石的挡土结构、承载地基、边坡稳定性等问题的计算,与传统的工程方法相适应,便于工程应用,而且对三维问题也提供了解决的途径。Kinematical Element Method (KEM) suggested by P. Gussmann is introduced in solving the problem of lateral earth pressure on retaining structures and computed results are given. Discrete model is applied to find the optimal upper limit solution. This method can be used in solving problems of stability of retaining structure, foundation and slope for soil and loose rock. It agrees with the traditional engineering methods and provides means in solving three dimensional problems.
