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.
Based on the percolation theory of porous media, another important infiltration channel, the fracture, is introduced into the percolation research of the media, and a pervasive percolation research method of porous media with pore fissures is proposed. According to the numerical calculation of the dual media of plane pore fissures, three important parameters of the dual media of pore fissures are obtained: porosity, fracture fractal dimension, the relationship between the initial value of fracture number distribution and percolation probability, and the percolation threshold The mathematical expression of the percolation law of the dual media of pore fissures is revealed.
