| 摘 要： | 根据黄石市板岩山危岩区的工程地质条件,建立三维有限元分析模型,考虑岩体节理和断层·采用自编的三维节理非线性程序GEOTL,模拟分析近100年来地下煤层逐步开采时山体的变形情况和开裂破坏情况,其结果与目前山体状况基本一致,说明地下煤层的开采是黄石市板岩山危岩体形成的主要原因。

| Abstract: | According to the engineering geological conditions of Huangshi Banyan Mount, A 3D finite element analytical model containing rock joints and faults is established. The coal deposits excavtion step by step is simulated using 3D joint nonlinear finite element program GEOTL. The deformation and failure features of rock masses obtained in this paper make a good agreement with the results by field measurements. It can be said that the coal deposits excavtion was the primary cause forming precipice cliff of Huangshi Banyan Mount. |
