| 摘 要： | 为了通过建立离散裂隙网络模型研究裂隙岩体的渗流规律,对建立的离散裂隙网络,借助图论方法描述裂隙间关系,在单个裂隙上,采用边界元方法,推导了求解渗流规律的具体公式。利用Matlab软件,程序实现通路的搜索及单裂隙渗流规律的求解。最后,通过随机生成的裂隙网络及算例调试程序证明:采用该方法可以快速、准确的实现渗流计算,为最终裂隙网络渗流规律的求解奠定了基础。

| Abstract: | The seepage law of fractured rock mass is studied by establishing the discrete fracture network model,which describs the fractured relationship by the graph theory.The boundary element method formula on the single fracture is deduced.By using the Matlab software the program is given of how to find the seepage path and to calculate the law of the seepage on the single fracture.Finally the procedures are tested by the fracture network which was born by the random method and the illustration.The results show t... |
