中文摘要：

节理岩体的剪切强度由结构面和相邻完整岩块的剪切强度共同决定,当结构面完全连通时,岩体的剪切强度完全由结构面决定。蒙特卡罗法能够根据结构面几何参数模拟岩体结构面的空间分布,通过深度优先搜索算法可搜索到连通的结构面,相对岩体而言,连通的结构面的剪切强度最小,即为节理岩质边坡的潜在滑动面,通过极限平衡法可以对一系列滑面进行稳定性分析。该方法是对节理岩质边坡稳定分析的补充。

英文摘要：

The shear strength of jointed rock masses is determined by the structural surface and the adjacent intact rock shear strength;When the structural surface is completely connected, the shear strength of rock mass is determined entirely by the structural surface. Monte Carlo method can simulate the spatial distribution of the discontinuity in jointed rock masses according to the geometry parameters of the structural surface; and then the connected structural surface can be searched via depth-first algorithm; and compared with the rock mass, the shear strength of the connected structural surface is the smallest; so it can be considered as the potential sliding surface of jointed rock slope. The stability of a series of sliding surfaces can be analysed by the limit equilibrium method. This method is the complement of the jointed rock slope stability analysis.
