摘　　要：阐述了岩体裂隙调查的方法、步骤,说明蒙特卡罗方法的基本思想,介绍了随机数的产生方法和几个分布函数,并利用蒙特卡罗方法模拟岩体裂隙网络、图论法建立岩体裂隙网络渗流模型,推导出渗流方程,并求解出裂隙段渗流速度。The investigation approaches and process of rock mass fracture were expounded and the basic thought of the Monte Carlo method is introduced. The production method of random numbers and several distribution functions were presented. The Monte Carlo method was used to simulate the rock mass fracture network. The graph theory method was used to establish a seepage model of rock mass fracture network of the simulated fracture network, to derive the seepage equations and to calculate the seepage velocity within the fracture segment.

关 键 词：裂隙网络 蒙特卡罗方法 渗流模型 图论法
