摘　　要：将裂隙岩体渗流视为裂隙网络流,示踪剂质点在裂隙网络中运动。以岩体裂隙网络水流模型为基础,应用仿真模拟技术模拟裂隙网络中的溶质运移规律。提出了裂隙网络中质点的转移概率和运移时间的计算方法,编制了相应的仿真模拟程序。将已有的实验结果和仿真模拟结果进行了比较,结果表明:该方法具有较高的可靠性和广阔的应用前景,是解决裂隙网络中溶质运移模拟的有效方法。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.
