| 摘 要： | 本文从工程地质中节理连通率的概念出发, 对有一组节理非常发育的不连续岩体建立了力学模型并推导了计算公式, 进而对边坡潜在滑动面在静水压力作用下从节理错动到岩桥剪断、从局部破裂到整体滑动逐步演化成滑动面的全过程进行了数值模拟和力学分析, 得到了有参考价值的结论。

| Abstract: | In this Paper, from the concept of link ratio of joints in engeneering geology, a mechanical modal for discontinuous rock mass with one set of joints is given and some calculation formula are developed, and then the whole process of a slip sureface gradually evolving from the potential slip sureface of a slope under the effect of hydro static pressure is simulated and analyzed. Finally a valuable conclusion is drawn. |
