| 摘 要： | 为了分析锡矿山锑矿床五窿道区老采空区上方建筑地基稳定性, 对该区的采空区进行了现场调查, 分析和探讨了采空区建筑物移动变形机理和采空区围岩失稳机理。采用ABAQUS对采空区建筑地基稳定性进行三维有限元模拟分析, 研究表明, 该区采空区都存在破坏的可能, 对老采空区必须进行处理。

| Abstract: | In order to analysis the stability of building foundation above the old goaf in Wulongdao mining area in Xikuangshan antimony deposits,some field survey has done on the mined-out areas in Wulongdao mining area to analyze and discuss distortion mechanism for the building foundation above old mined-out areas and instability mechanism for surrounding rock masses of old goaf.Based on ABAQUS,the stability for building foundation above the goaf is calculated with three-dimension finite element method.Results show... |
