地质体有着十分复杂的结构和构造,因此,如何掌握地质体中各点的位移规律和应力分布规律,对工程地质研究,预测矿山边坡稳定性和地下工程稳定性,地震预测和预报以及地质构造形变的规律都是十分重要的。数值模拟是研究形变规律和应力场分布的重要手段之一。有限单元法是数值模拟的有利计算工具之一,国内外已得到广泛的应用。地质体中各点的形变及应力分布问题实际上是个三维问题。有些情况将它简化为二 Therefore, how to grasp the regularity of displacement and stress distribution of every point in the geological body, how to forecast the prediction of the slope stability and underground engineering stability, earthquake prediction and prediction, geology The rules of tectonic deformation are all very important. Numerical simulation is one of the important methods to study the deformation law and stress field distribution. Finite element method is one of the favorable computational tools for numerical simulation, and has been widely used both at home and abroad. The deformation and stress distribution of each point in the geological body is actually a three-dimensional problem. In some cases it is reduced to two
