Abstract: The seepage in fractured rocks was regarded as the fracture network flow.The tracer particles moved as the water flow in the fracture network.Based on the flow model of fracture network for rocks,laws of solute transport in the fracture network were modeled by emulation technique.A method for the of transfer probability and transport time tracing the motion of particles in the fracture network was put forward.Furthermore,the corresponding simulation program was developed.At last,compared the experimental results with the simulated results,it was shown that the emulation simulation was of considerable reliability and was an effective method.The method could model the laws of solute transport in the fracture network conveniently with of wide application prospect.
