Abstract:Combining with percolation theory,the composition characteristic of fractured rock seepage network is analyzed according to the statistic data and seepage characteristic of discontinuity in practical engineering;and the similarity problem of three-dimensional block cutting technology and percolation theory in fracture classification is also studied. The identification module for water-block characteristic on seepage fractures plane is added based on three-dimensional block cutting technology;and three-dimensional seepage network searching algorithm is formed finally to solve the problem that three-dimensional seepage network is difficult to be established. According to Louis formula and generalized Darcy law,a program named 3D-Network-Seepage.f90,which can solve the problem of three-dimensional seepage network searching in fractured rock and analyze steady seepage,is developed by this algorithm. Combining with a classical example,this method is proved that it not only can form objective and valid seepage network,but also reflects the laws of water movement on fracture plane and the actual flow trend in fracture network. However,this method is expected to be proved in practical project in the future.
