摘　　要：文章简要介绍了EH-4电导率成像技术的原理,利用其在贵州西线高速公路槽箐头隧道和惠水县团坡水电站引水隧洞的工程地质勘探中,均收到了较好的勘探效果,表明EH-4电导率成像技术具有探测深度大、不受高阻屏蔽、勘探精度及工作效率高等优点。The paper briefly introduces the principle of imagery technology of specific resistance EH- 4. It was applied in geological investigation of Chaoqiantou tunnel of highway located on the west part of Guizhou Province and the water tunnel of Tuanpo Hydropower Station located Huishui County, and the application results were better. The writer has made known that the technology had some advantages such as large detectable depth, high detecting precision and work efficiency, feature that high resistant could not influence its work and etc.
