| 摘 要： | 在孔隙介质逾渗理论的基础上，将另外一个非常重要的渗透通道——裂隙引入到介质的逾渗研究中，提出了更为普遍的孔隙裂隙双重介质的逾渗研究方法.通过对二维平面孔隙裂隙双重介质的数值计算，得到了孔隙裂隙双重介质三个重要参数：孔隙率，裂隙分形维数、裂隙数量分布初值与逾渗概率的关系，给出了孔隙裂隙双重介质逾渗阈值的数学表达式，揭示了孔隙裂隙双重介质的逾渗规律.关键词：孔隙裂隙双重介质逾渗逾渗阈值

| Abstract: | Based on percolation theory of porous medium, the fracture as a very important permeability channel is taken into account in the theoretical research on percolation of medium. The research method on percolation of more general porous and fractured double-medium is put forward. Through the numerical calculation on the pore and fracture in donc in 2D, the relation between percolation probability and important parameters such as porosity, fracture fractal dimension and initial value of fracture distribution are obtained. The mathematical formula on percolation threshold of porous and fractured double-medium is also obtained. The percolation law of pore and fracture is further shown. |
