采空区地基稳定性有限元模拟
|
摘要
在塌陷区开发利用过程中,必须对塌陷区上新建建筑物的地基稳定性进行核算,但是传统的计算公式和方法,有其本身的局限性,很难得到合理的分析结果。以某地的地质条件为基础,通过有限元分析,对塌陷区的开发利用过程中地基稳定性和采空区应力场的变化做了数值模拟,得到了采空区地基稳定性的一般条件。并对有限元数值模拟方法在这方面的应用做了探讨。
In the course of developing in subsidence area, the base stability must be checked and calculated, but there is one's own limitation in traditional calculation formula and method , it is very difficult to get the rational analysis result. Based on some geological conditions of ground, this paper adopt finite element analyse method to make the numerical simulation in conformity with the change of the force field on ground stability, there is the general condition of the empty district ground stability. And it has done the discussion to the application in this respect of numerical simulation method of finite element.
