利用数值方法模拟土石坝温度场研究土石坝渗漏

Leakage is a universal problem for most of the composite dams all over the world, and finding out the location, the quantity and the bound of the leakage are the first and most important processes to solve the leakage problem. Using the temperature field to detect the dam leakage is a new and effective method. Based on the dam temperature field distribution influenced by 2-D seepage and the finite element method, a new method, which uses the temperature field analysis to detect the dam leakage, is proposed in this paper. The temperature field distribution of different types of dam leakage can be simulated by giving the dam different seepage parameters. The leakage characteristic in different positions of the dam can be determined by the contrast between the simulation and the field data from the drills. Finally, the method is proved correct and feasible by a project example.
