摘要
针对双重裂隙系统渗流,提出断裂损伤渗流张量模型- 该模型将主干裂隙网络模拟为非连续介质模型,将裂隙岩块模拟为具有一定开度的扁平圆盘裂纹- 由裂隙统计分析和Monte Carlo 法产生随机网络系统- 根据断裂力学理论,按照裂隙的断裂扩展过程建立起渗流张量的演化方程-
To simulate the seepage in double fracture systems, a seepage tensor model in rupture-damage is developed According to this model, the dominant fracture network is simulated as the discontinuous medium, the fracture rock, issimuiafed as a flat disk flaw with a certain opening degree structures, a random network system conforms to the cranny statistic analysis and the Monte Carlo method On the basis of fracture mechanics, an evolvenent equation of the seepage tensor is established according to the expanding course of cranny fracture
