【摘要】 为获得有效的老采空区上方地基稳定性评价方法,以淮北金岩、相南小区为例,根据收集的地质资料,应用概率积分法对采空区的沉陷变形及影响范围进行了定量评价;在结合建筑物荷载影响深度与老采空区冒落裂缝带发育高度相对位置关系的研究的基础上,对采空区上方地基的稳定性进行了定性评价,论证了在该小区建设建筑物的可行性;对采空区上方建筑物提出了相应的安全保护措施,为该小区建设提供了技术依据。更多还原

【Abstract】 In order to have a method to effectively evaluate the stability of the foundation above the old mining goaf,taking Huaibei Jinyan and Xiangnan Residential Area as example,according to the geological information collected,a probability integration method was applied to the quantitative evaluation on the subsidence deformation and the influence area of the mining goaf.Base on the relationship between the loading of the surface building affected to the depth and the the development height of the falling fracturing zone in the mining goaf,a qualitative evaluation was conducted on the stability of the foundation above the mining goaf.The feasibility to set up the buildings in the residential area was verified.Related safety and protection measures were provided for the buildings above the mining goaf and could provide the technical references to the building construction in the residential area.更多还原
