摘要
为了探索山西采煤区地质灾害的成因,研究采空区对地表变形的影响,以太原西山蛇盘兔地区为例,采用有限元数值模拟软件,计算并分析采空区形成后岩体内部的应力应变特征,研究分析采空区引起地表变形的规律。
In order to explore the cause of Shanxi coal mining area geological disasters and study the effect of mined-out area on the surface deformation,takes Shepantu area in Taiyuan Xishan as an example ,the finite element numerical simulation software is used to calculate and analyze the characteristics of stress and strain inside the rock mass with mined-out area,study the deformation law of the surface caused by the mined-out area.
