开采沉陷的三维数值仿真与计算模型探讨

应用有限元法对某矿开采导致的地表沉陷进行了三雏数值分析，并就该地质开采条件分别对平面和三雏情况、有无弱面情况进行了对比计算和分析。结果表明，设置弱面的三雏计算模型更符合工程实际。

Study on 3 - D Numerical Simulation and Calculation Models of Mining Subsidence

Using finite element method, 3 - D numerical analysis is made on the surface subsidence induced by coal mining in some mine. Based on the geologic mining condition, contrastive calculation and analysis are conducted respectively under the conditions of 2 - D and 3 - D, with and without weak face. The results indicate that 3 - D model with weak face more agrees with engineering practices.
