| 摘 要： | 提出岩质边坡沿软弱结构面滑移-剪切的三维稳定分析方法。在分析模型中,下滑体沿滑动面下滑,在其他的面上则产生剪切破坏。在结构面上满足莫尔库伦破坏准则,把剪切面上的摩阻力向下滑方向投影,由下滑体的力学平衡条件求解出未知力,通过迭代可以求得稳定系数。同时推导了摩阻力倾向与倾角的计算式,编制了相应的程序,并利用这个程序,研究了边坡长度、岩层与坡面夹角等因素对边坡稳定系数的影响,比较了三维分析与二维分析的差别。

| Abstract: | A 3D equilibrium analysis method was presented to evaluate the stability factor of rock slope based on slip-shear failure model.In the failure model,slide slipped along a weak rock direction,and shear crack occurred on the other planes of the slide.The slip and shear crack interfaces satisfied the Mohr-Coulomb Law.The friction was projected along the slip direction,and the normal force on the slip interface was calculated by the force equilibrium analysis.The stability factor of rock slope was obtained by i... |
