摘要
构造应力场的数值模拟是地质动力区划方法的重要组成部分。为此.本文开发了两个程序,一个是有限元程序,用于水平剖面应力计算,一个是边界元程序。用于铅直剖面应力计算。在中俄专家用地形图等综合方法确定出的矿区断块系统及最大主应力方向的基础上,对东北某矿区构造应力场进行了数值模拟。
The numerical simulation of tectonic stress field is a important part of geologic-dynamic area distribution method. The paper designs two programs, one is FEM program for determining the stresses in horizontal profile, another is BEM program for determining the stresses in vertical profile. Based on the fault block system and the maximum principal stress direction in mining area, determined by using the systematic method including the topographical map used by ChineseRussian experts, the numerical simulation has been carried out for the tectonic stress field of a mining area in E-N China, and the high stress area has been determined.
