| 摘 要： | 以某露天采场高边坡为例，根据边坡岩组的划分建立准三维计算模型，在MohrCoulomb本构模型上，采用有限差分法，应用FLAC^3D程序，模拟了该边坡在天然工程概况下的局部稳定性及其变形特征，以及考虑了优势节理J3、J5后的整体稳定性及其变形特征，获得了边坡变形机制，验证了边坡破坏模式和主要影响因素。

| Abstract: | A opencut mining slope was taken an example.The quasi three dimensional calculation model was created according to petrofabric division.The stress distribution,failure mode and mechanical mechanism were established by finite difference numerical analysis under Mohr-Coulomb constitutive model.Then the mechanism of slope deformation and the main factors were obtained. |
