电阻率影像法在堤坝渗漏中的应用研究

The Application Study of Dam Leakage with Resistivity Tomography

目的:电阻率影像法以其观测密度大、分辨率高等优点得到了广泛的应用。在解决堤坝渗漏方面,也有着很好的应用前景。方法:通过分析常见的堤坝渗漏模型,给出了电阻率影像法在解决堤坝渗漏上的工作和解释方法。结果:最后,以土石坝为例,用三维有限元法对堤坝渗漏模型进行了模拟。结论:对结果进行了解释,取得了较好的效果。

Objective:The resistivity tomography method has been widely applied in virtue of high density, high resolution and so on. It also has a good future on detecting leakages of dams. Meterials and Methods:Through analyzing the popular models of leakages of dams, the paper introduces the methods of work and interpretation on resolving leakages of dams.Result: Finally, using 3-D finite element method to model the leakages of an embankment dam,for example. Conclusion: Interpreting the result of modeling, it gets a satisfactory effect.
