电阻率测深法在云南省玉溪市抗旱找水定井中的应用

介绍了在云南玉溪抗旱找水定井的工作实例，在地质、水文地质调查工作的基础上，采用电阻率测深法在重点地段开展工作，在充分分析、研究含水层电性特征的基础上，对实测电阻率测深曲线进行对比解释，最后确定井位，通过所施工钻孔验证了物探推断成果符合实际，并且单井涌水量均大大超出当地所需水量，取得了良好的水文地质效果，得到了当地政府及群众的一致好评。同时，也为在高原地区基岩及“红层”找水积累了一定经验。

Application of Resistivity Sounding Method in Looking for Water and Wells Drilling in Yuxi City of Yunnan Province

Practices of looking for water and wells drillings in Yuxi city of Yunan province has been intro- duced in this paper. On the basis of geological and hydrogeological investigation, by using resistivity sounding method in the key areas, through analysis on electrical characteristics of the aquifer, the meas- ured resistivity sounding curve has been interpreted and compared, the wells drilling spots have been determined as well. Through the construction drillings, it is verified that geophysical inference results are consistent with the actual condition, average single well water yield is far beyond the required water volume in local region. It has obtained a good hydrogeological effect, and praised by local government and the mas- ses. It will also provide some references for looking for water in the bedrocks in the highlands and in the ＂ red beds＂.
