煤矿采空区场地地基稳定性及适宜性分析
摘要:结合一煤矿采空区场地作为新建高层住宅小区场地，通过开采条件、地表移动变形综合确定煤矿采空区的稳定性;采用工程类比法、采空区特征判别法、活化影响因素分析法、地表剩余变形判别法等判别采空区场地工程建设适宜性;建议采空区场地采取吸收地表沉陷变形的柔性措施和抵抗地表沉陷变形的刚性措施来确保拟建建筑物的安全。
Abstract:A goaf is proposed as the ground of a new high-rise residential area. The stability of coal mine goaf is determined synthetically by mining conditions and surface movement deformation. Engineering analogy method, goaf feature discrimination method, activation influence factor analysis method, surface residual deformation discrimination method and other methods were used to determine the suitability of goaf site construction. It is suggested that flexible measures to absorb surface subsidence deformation and rigid measures to resist surface subsidence deformation should be adopted to ensure the safety of the proposed building.
