摘要: 基于对北京市房山区史家营乡大村涧村的现场调查成果,借助于有限元分析软件建立了三维数值地质力学模型。通过对大村涧村采空区上方矸石—岩土混合型边坡在天然状态与饱和状态下安全系数及采空区上方房屋的沉降变形的计算分析。最终对采空区上方矸石—岩土混合型边坡的稳定性及滑坡危险性进行评价。

Abstract: Based on the survey results of the Dacunjian Village, Shijiaying Town, Fangshan District of Beijing, a three-dimensional numerically geo-mechanical model was established by means of finite element analysis software. And the slope stability and landslide hazard was ultimately evaluated through calculation analysis of the settlement and deformation of gangue-rock hybrid slope in natural and saturated state.
