数值方法在大坝破坏分析中的应用

Review of the application of numerical methods to dam failure analysis

论述在大坝破坏分析中数值计算方法的发展过程和现状.简述目前广泛使用的结构力学分析法、连续变形分析法、非连续变形分析法、整体稳定分析法的基本原理和单元剖分思路,逐个分析它们的适用范围和存在的不足之处,指出数值计算方法亟待解决计算结果对单元网络剖分的依赖性等关键和基础性问题以及进一步努力的方向.

An introduction was given to the development process and current situation of the numerical methods applied to dam failure analysis. A comparative analysis was made of the basic principle and idea of element division of some methods widely used at present, including the structural mechanics analytical method, continuous deformation analytical method, discontinuous deformation analytical method, and the monolithic stability analytical method, together with their advantages and suitable scope of application. Finally, some key problems to be solved urgently, such as the dependence of the calculated results on element division, etc. and the direction for further research were pointed out.
