摘　　要：蚁穴、裂缝、渗漏等隐患会对土质堤坝的安全运行产生不利影响。利用高密度电法定期对堤坝隐患进行探测是及时发现隐患的有效方法。因此,对土质堤坝内部隐患直流电场响应特征的掌握是实现对物探结果解译及隐患类型识别的先决条件,对堤坝隐患的探测具有重要意义。笔者利用Comsol Multiphysics有限元数值模拟软件,建立蚁穴、裂缝、渗漏等常见隐患的模型,探讨不同类型隐患在高密度电法反演剖面上的异常特征,并将这一成果应用到河南省某水库的隐患探测中,取得了较好的效果。Hidden defects such as anthills,cracks,and leakage can adversely affect the safe operation of earth dikes.The use of high-density electricity method to regularly detect hidden defects of dikes and dams is effective.Therefore,understanding the response characteristics of DC electric field of hidden defects inside earth dikes is a prerequisite for the interpretation of geophysical survey results and the identification of hidden defect types,which is of great significance.In this paper,the finite element numerical simulation software is used to establish models of common hidden defects,such as anthills,cracks,and leakage,and the abnormal characteristics of different hidden defects on the high-density electrical inversion profile are studied.Moreover,this result is applied to the hidden defect detection of a reservoir in Henan province,which is proved to be effective.
