EH4电磁成像系统在水库大坝隐患探测中的应用

Application of EH4 Electromagnetic Imaging System to Hazard Exploration of Dongfeng Reservoir Dam in Yunnan

对水利设施的现状进行检测,查明隐患及其存在部位,为水利工程设施的整治和修复方案的制定提供可靠的依据,是现代地球物理方法发挥作用的一个广阔领域。本文介绍了EH4电磁成像系统的原理、特点及在云南东风水库坝体隐患探测中的实际应用,说明该方法可以对坝体渗漏位置、断裂及破碎等地质构造进行有效探测。

In order to provide a reliable basis for remediation and restoration of water conservancy facilities,it is necessary to detect the status of water conservancy facilities and to indentify the safety hazards and their positions.This paper describes the principles,characteristics,and procedures of EH4 electromagnetic image system,and introduces its practical application in the safety hazards detection of Dongfeng reservoir dam in Yunnan.And this application proves that the method can effectively detect the dam break and other geological structures.
