【摘要】 拉格朗日元法是一种常见的数值计算方法,以有限差分程序FLAC软件为例,简单论述其原理,分析了它的优缺点并叙述其工作流程,表明其非常适合解决非线性、大变形问题。同时通过介绍了在国内外地学方面的一些应用实例,对数值模拟技术在国内地学方面的应用和研究提出一些建议。更多还原

【Abstract】 The principle of Lagrangian element method, a common numeric analysis, is briefly discussed. Advantages and shortcomings of the method are discussed using FLAC software, and work flows of the software are also presented. It is shown the method is very suitable to resolve non-linear and large-anamorphic problems. Some geo-scientific applications in home and abroad are presented and some suggestions of technology using numeric simulation in geosciences are also put forward.更多还原
