摘　　要：岩体边坡在强震作用下往往会产生滑动残余位移。这种位移是边坡稳定性评价的重要参量。本文利用块体动力学原理推导出层状和块状岩体边坡地震滑动位移微分方程式，并编制了相应的计算程序。Residual sliding displacements of rockmass usually occur on slopes by the effect of strong earthquakes. The displacement parameters are important for evaluating seismic stability of the slopes. In this paper the dynamic equilibrium equations for calculating sliding displacement of rockmass with layer and block structures on slopes are deduced, the corresponding calculation programs are compiled and the calculation results of an example are given .
