摘要
岩体结构面三维连通率是一个内涵空间岩体稳定性评价的重要参数,它完全不同于常规的与水文地质或岩体水力学相关的连通率。由于岩体中结构面发育的随机性,采用一般的方法很难得到岩体结构面在空间的三维连通率。介绍的岩体结构面三维连通率是基于现场工程岩体结构面三维网络数值模拟的基础之上,采用理想截面投影法来求取工程岩体关键部位、特定方向上的三维连通率,并通过计算机编程来实现计算,直接应用于工程中。
Three-dimensional connectivity of rock mass fractures is an important parameter which has the connotation of evaluating rock mass stability. It has the meaning of hydro-rock mechanics which is totally different from the meaning of connectivity related to the hydrogeology. Because of the randomness of fractures in rock mass, it is very difficult to obtain the three-dimensional connectivity of rock mass fractures by general method. A new method to obtain the three-dimensional connectivity of rock mass fractures is described based on the in-situ engineering rock mass fractures of three-dimensional network numerical modeling to obtain the three-dimensional connectivity in special dip direction and key section of engineering rock mass by ideal section plane projection. A computer programming is written by authors to realize the calculation; and its result is directly applied to practical engineering.
