【摘要】 以概率积分法预计的开采沉陷作为输出结果，利用位移反分析的方法，结合三维弹塑性有限元数值计算，分析评价了老空区地面上方增建多层建筑物后地面沉降与建筑物稳定性，提出了工程设计措施。更多还原

【Abstract】 In this paper,the surface settlement due to the mining estimated by the probability integrating method is taken for the output result,the surface settlement and builing’s stability is analysed and evaluated as the multi-layer building built above old workings by means of displacement back analysis method and combined the three-dimensional elastic-plastic finite element calculation.The engineering design measure is put forward.更多还原
