摘　　要：针对深部矿体开挖岩体移动变形的特点,分别运用ANSYS软件和随机介质方法对开挖引起的地表下沉进行二维模拟分析.通过将理论计算结果与实测值进行对比,结果表明,运用随机介质方法算出的理论值与实测值比较吻合,而ANSYS软件只能预测最大下沉值.本研究结果可供今后进一步探索ANSYS软件在岩土工程中应用提供参考.According to the characters of the rock mass displacement and deformation for the deep ore deposit excavation, the two-dimensional problem of surface subsidenc due to underground mining is analysed by stochastic medium method and the software ANSYS respectively. By comparing the results of theoretical calculating to the measured data, the results show that the theoretical value calculated by the stochastic medium method is in agreement with the measurement data, while the software ANSYS only can predicte the maximum subsidence. This research can be used to study the further application of the software ANSYS in the rock and soil engineering.
