岩体多重裂隙网络渗流模型研究

将岩体中的各种裂隙和孔隙按规模和渗透性分为４级处理，即一级真实裂隙网络、二级随机裂隙网络、三级等效连续介质体系和四级连续介质同体系。各级裂隙（孔隙）都形成各自的裂隙网络，并以水量平衡原理为基础建立各级裂隙网络之间的联系，组合形成岩体多重裂隙网络渗流模型，从而较全面地反映了地下水在岩体中的运动规律，并进行了工程实例分析。

ON SEEPAGE MODEL FOR ROCK MASS OF MULTI-LEVEL FRACTURE NETWORK

According to the scale and the permeability,the fractures and pores in rock mass are divided into four levels,i.e.,the level 1 real fracture network,the level 2 random fracture network,the level 3 equivalent continuum and the level 4 continuum.The seepage model for rock mass of multi level fracture network is proposed by combining the fracture networks of four levels,in which the water balance is sustained.A engineering example is also given to show the applicability of the proposed model.
