Abstract: The discrete fracture network model is confined in the application of rock mass seepage because of the numerous discontinuities in engineering rock mass. This makes investigators search mature equivalent continuum medium model in theory substitute the discrete fracture network model. Thus the research on porous medium hydraulic equivalence of fracture rock mass is necessary. Based on plenty of field measured fracture data, a statistical analysis about fracture density, azimuth, size, continuity, jaw opening is made, the random model of discrete fracture network is established on Enhanced Baecher model. The Monte Carlo random simulation is used in fracture network random simulation, thus the three-dimensional discrete fracture network figure of different dimension is obtained. On the basis of the three-dimensional discrete fracture network the REV is calculated, the equivalent continuum medium model can be analytical rock mass seepage.

Key words: fracture rock mass, porous medium, hydraulic equivalence, 3-D fracture network, Monte Carlo simulation
