摘　　要：以某水库土石坝下的压煤开采工程为背景,结合其他矿区压煤开采的实测结果,应用概率积分法的数学模型进行了开采沉陷变形预计,研究了土石坝由于地下开采而引起的变形和破坏特征以及对土石坝的安全产生的影响。通过数值模拟以及水文计算的结果分析,开采沉陷变形对水库的防洪安全产生了很大的影响。Taking the mining coal under a reservoir earth dam project as the background, combining with the measuredresults of mining coal from other mines, this paper conducted a mining subsidence and deformation prediction by themathematical model of probability integration method. And studied the deformation and failure characteristics caused by theunderground mining as well as affected by the earth dam. By the results of numerical simulation and analysis of hydrologiccalculations, subsidence deformation of embankment dams had a great impact on the control flood safety of reservoir.
