三维离散单元法及其在滑坡分析中的应用

Three-dimensional discrete element method and its application in landslide analysis

摘要: 介绍了三维离散单元法的基本原理,编制了相应的C语言程序,并对具体的滑坡实例进行了模拟,发现计算结果与已有研究成果较为一致,表明三维离散单元法是一种可以动态模拟山地滑坡行为的比较适宜的数值方法。

Abstract: The fundamental of three dimensional discrete element method is introduced,a practical example of landslide is simulated with the C program developed by the authors,and some reasonable results consistent to the existing data are obtained.It can be concluded that the three dimensional discrete element method is a suitable method to dynamically simulate landslide.
