摘　　要：EH-4电磁成像系统具有勘查深度大、轻便高效、反映成果直观等特点。在寻找地下水及水文地质方面得到了广泛的应用。为帮助青海省平安县严重缺水南部山区寻找地下水,选用了EH-4电磁系统进行剖面探测,通过确定该区内隐伏断层的位置及断层破碎带,进行构造找水,实践证明:以其他电磁法相比,EH-4电磁成像系统穿透力强、不受浅部高阻层的影响,适用性强、效率高。The EH- 4 electromagnetic imaging system has great exploration depth,light efficiency,reflect the results of visual features. It was widely used in searching for groundwater and hydrogeological aspects. To help an acute shortage of water in Pingan county of qinghai province southern mountains looking for groundwater,select the profile EH- 4 electromagnetic system detection,by determining the area within the concealed fault location and fault fracture zone,the article carries out to construct water. The practice shows the EH- 4 electromagnetic imaging system is strongly penetrating without influence of shallow high resistance layer under comparation with other electromagnetic methods and it has strong applicability and high efficiency.
