基于Matlab的裂隙岩体渗透路径搜索

在随机生成的裂隙网络中,如何快速确定渗透路径是进行下一步渗流计算的前提和关键。借助图论方法描述裂隙间关系,利用Matlab软件,依据裂隙真实分布的特点,首先确定两圆心距过大及平行裂隙间的相离关系,大幅减少了程序中需要求解的方程的数量,加快了运行速度,实现了裂隙岩体三维网络渗流的渗透路径快速搜索。最后通过随机生成的裂隙网络调试了改进的程序,验证其可行性。结果表明:采用笔者改进的算法可正确找到搜索路径,并可大幅缩短搜索时间,为下一步渗流计算打下了良好的基础。

Searching infiltration route of fractured rock mass based on Matlab

In the random generation of fracture network,how to determine the infiltration route fastly is the premise and key for the seepage calculation.This paper makes a seepage path by describing fractured relationship using the graph theory,and Matlab software,based on the characteristics of real fissures,identifies the separate relationship of the two central distance too great and parallel firstly,reducing the need for the number of equations to accelerate the run rate.Finally the procedures are tested by the fracture network which was born by the random method to test its feasibility.The results show that using the author's improved search algorithm can find the right seepage path,thus significantly shortening the search time and laying a good foundation for the seepage calculation.
