摘　　要：堤坝渗漏隐患一直是防洪工程中亟待解决的问题。本文分别利用电流场和渗流场的电势微分控制方程与流速势微分控制方程的相似性原理,采用Comsol软件对堤坝管涌渗漏模型进行数值模拟,讨论了由管涌渗漏引起的电流密度矢量分布和电位差异常形态特征.同时以实际场景中的某堤坝渗透探测为例,对理论研究进行实验验证。实验结果表明,野外工程实例中得到了与模拟结果相对应的电位差异常形态特征,可为实际堤坝渗漏检测工作提供理论支撑。Hidden leakage of dams has always been an urgent problem to be solved in flood control projects. This paper uses the similarity principle of the potential differential governing equation of the current field and the seepage field and the flow velocity differential governing equation respectively, and uses the Comsol software to numerically simulate the dam piping leakage model. The constant morphological characteristics of current density vector distribution and potential difference caused by piping leakage are discussed, and the theoretical research is verified experimentally by taking the seepage detection of a dam in an actual scene as an example. The experimental results show that the constant morphological characteristics of potential difference corresponding to the simulation results are obtained in the field engineering example,which can provide theoretical support for the actual dam leakage detection work.
