Abstract

 The fractures or crustal faults have complete control over hydrological property of each fractured rock mass. This paper proposed the multi-scale numerical mass-transfer simulation model in fractured rock mass by using the discrete fracture network model , random walk model and generalized finite element approximation. In this numerical simulation, the Logistic regression model and Weibull distribution was employed as the space distribution of permeability coefficients. As a numerical result, the bleeding channel flow in fractured rock mass model was revealed numerically.
