针对滑坡的物质特征和运动特征，对其进行适当假设并将之视为粘滞系数较大的不可压缩流体，给出了滑坡供述滑坡运动过程的控制方程，如质量连续式、运动方程式、本构方程以及状态方程等，基于有限体积法(FVM)原理专门编写了三维计算程序用于模拟滑坡的运动。最后以黄河上游某水电站坝后滑坡为例，用该程序模拟其动态滑动特征，预测其可能成灾范围，指导该工程的布局和设计。 

关键词: 滑坡, 动态过程, 有限体积法, 成灾范围预测

A landslide can be considered as incompressible fluid with high viscidity in view of their characteristics of materials and movements. Such governing equations as mass conservation law, momentum conservation law, constitutive equation and other state equations were established to describe the landslide motion. Based on these equations and FVM (Finite Volume Method), a special 3-D numerical modeling program was designed to simulate the dynamic movement of landslides. Using the grogram, a landslide of a hydropower station located at upstream of the Yellow river was modeled to predict its dynamic movement features and deposit scope and to guide the plan and design of the project.

Key words: Landslide, Dynamical motion, Finite volume method, Prediction of deposit scope of landslide.
