| Abstract | 针对裂隙岩体提出了一种基于双重逾渗模型的渗流系数分析方法。通过变参数研究,考察了岩体中渗流和孔压分布的不均匀;根据裂隙长度的不同将岩体分为"孔隙控制"渗流模式和"裂隙控制"渗流模式。这种模型不仅能够同时考虑孔隙和裂隙的作用,而且在模拟大规模裂隙网络时更加快捷简便。 |
| Other Abstract | A method is presented based on the double percolation model for analyzing the permeability coefficient of fractural porous rock.The results computed by this model are close to that by fractural permeability tensor theory when the porous percolation is neglected.The non-uniformity of permeability and the pore pressure are investigated by parametrical analysis.It is shown that rocks can be divided into "pore-controlling" and "fracture-controlling" modes according to the fracture length.The method can not only consider the effects of pores and fractures together,but also be more fast and simple during the simulation of fracture network in large scale |
