| 摘 要： | 应用节理岩体三维网络模拟技术建立结构面在三维空间分布的概率统计模型，将连通率的概念和求解均建立在岩体潜在破坏路径之上，通过连通率的求解米搜索岩体的最可能破坏路径。在搜索结构面和岩桥搭接组合破坏的临界路径过程中，应用了具有鲜明生物背景的遗传算法，并将这一结果应用于实际岩体工程，取得很好的效果。 |

| Abstract: | D persistence of rock mass is a very important factor that influences the mechanical behaviors of jointed rock mass. Based on the 3D probability distribution model of the discontinuities established through the 3D numerical modeling technique of network,a new conception and solution of 3D persistence of rock mass are put forward on the basis of the potential failure path of jointed rock mass. With the solution of persistence,the most possible failure path in rock mass can be found out. In the process,the theory of genetic algorithm with the characteristics of biological background is adopted to determine the optimized 3D persistence in complicated jointed rock mass. This new method has been used in a practical hydroelectric project,and the result shows that the new method is available for engineering design. |
