In this dissertation, the author presents a model of transforming element fracture net into element equivalent hydraulic conductivity tensor. this model can effectively reflect the obvious anisotropy and non - homogeneity of fracture rock seepage and makes it easier to simulate the various aperture fissure and display the fundamental characteristics of discrete fissure net. in addition, the model is can also make the best use of the sound theoretic foundation of equivalent continuum model
< wp = 5 > 5 、本文提出將單元裂隙網路轉化為等效單元滲透張量的裂隙網路轉換模型（單元網路模型） ，具有真正體現裂隙巖體滲流明顯的各向異性和顯著的非均質性、易於模擬變隙寬裂隙、基本顯示巖體裂隙網路滲流的基本特點、充分利用連續介質模型雄厚的理論基礎等特點。 -
Firstly in this part, computer simulation methodology based on the baecher model for generating network of discrete fractures was presented, which includes the follow details : probability distributions of fracture density, orientation, trace length, size, and aperture and estimation of their statistical parameters ; stochastic models of fracture network ; monte - carlo ' s simulation method ; numerical simulation procedure and technicality. then, boundary element method was used to calculate flow through the generated fractured network. assuming single fracture as a two - dimension inexpressible isotropic porous media, boundary element method equations for flow in single fracture and then in fracture network were derived using the weighted residual method

According to the existing studies of the basic law of fracture seepage, there are two sharp contrastive relations between seepage discharge and aperture : super - cubic and sub - cubic. similarly, there are also two opposite relations between seepage discharge and relative roughness : positive and negative relations
2 、現有的裂隙滲流基本規律的研究成果中，滲流量與隙寬出現兩種截然相反的關系：超立方和次立方關系；滲流量與相對粗糙度也存在兩種相反的關系：正相關和負相關關系。 -
