To Calculate Hydraulic Conductivity Tensor of Fractured Rock Mass by Monte-Carlo Analogy Technique

裂隙岩体的渗透系数张量是一个非常重要的岩体水力学参数。本文采用结构面现场测量及统计分析方法建立岩体结构的概率模型 ,进而采用 Monte-Carlo模拟技术生成岩体裂隙网络模型 ,由裂隙网络模型中的连通裂隙计算岩体的渗透系数张量 ,并给出了工程应用实例。

The hydraulic condutivity tensor of fractured rock mass is a very important parameter of rock mass hydraulics. The probability model of rock mass structure and the fracture network model of rock mass are established by means of field measurement and statistic analysis and Monte\|Carlo analogy technique. The hydraulic conductivity tensor in obtained through connecting fractures in the fracture network model. Case history of application in project is given herein.
