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。
基于對北京市房山區史傢營鄉大村澗村的現場調查成果,藉助于有限元分析軟件建立瞭三維數值地質力學模型。通過對大村澗村採空區上方矸石—巖土混閤型邊坡在天然狀態與飽和狀態下安全繫數及採空區上方房屋的沉降變形的計算分析。最終對採空區上方矸石—巖土混閤型邊坡的穩定性及滑坡危險性進行評價。

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.
