本文依据北京市房山区史家营乡大村涧村的调查成果,借助于有限元分析软件,建立居住区附近影响范围内的边坡三维工程地质力学模型和弹塑性模型,利用有限差分法分析,对单一矸石堆边坡和矸石-岩土混合型边坡,进行计算分析,对比分析了这两种边坡在天然状态下与饱和状态下的安全系数,最终进行了边坡危险性评价。

According to the survey results of Dacun and Jiancun villages of Shijiaying Town, Fangshan District, Beijing, we have established the 3-D engineering geomechanics model and elasticity-plasticity model on the slope stability near the residential areas, which are established by finite element analysis software. By the finite difference method, we analyze and contrast the safety coefficients of the two kinds of slopes （single waste rock pile slope, waste rock rock mass mixed slope） between the natural and saturated states. Finally, the slope risk has been evaluated.
