Abstract: Taking leakage detection of Xiaopaiwu dam as an example, comprehensive geophysical prospecting method based on spontaneous electric field method, flowing field method and high-density resistivigy method is put forward. This paper introduces the principle, method and conclusion of the comprehensive geophysical prospecting and described quantitatively about the leakage passage and entrance. The successful application of this method provides a new way for rapid detection of leakage.

Key words: reservoir leakage, comprehensive geophysical prospecting method, spontaneous electric field method, flowing field method, high-density resistivity method, leakage passage, leakage entrance

摘要: 以湖南省小排吾水库大坝渗漏隐患探测为例,提出基于“自然电场法”、“流场法”和“高密度电法”的综合物探法技术方案,介绍了综合物探法的工作原理、方法及结论性成果,并对小排吾水库主副坝渗漏通道、库区渗漏入口进行了定量描述。该技术方法的成功应用为水库渗漏入口、渗漏通道的有效快速探测提供了新的思路。
