可控源音频大地电磁法在地下水勘查中的应用研究

APPLICATION OF CSAMT TO THE SEARCH FOR GROUNDWATER

根据可控源音频大地电磁（ＣＳＡＭＴ）法进行地下水勘查时取得的大量资料，通过总结、分析与研究，提出了在蓄水构造的断层上，ＣＳＡＭＴ测量的视电阻车断面等值线图呈中间低、两侧高的异常特征．利用这一模式解决了在山区、半山区，很多地球物理方法难以解决的地下水勘查问题．经打井验证，成井率很高．

Through analyzing a vast amount of data by prospecting the groundwater using CSAMT(controlled source audio magnetic telluric), we sum up the apparent resistivity y features which show low in the central part and high in the both sides corresponding to the warel-bearing structure.Using this features,we have solved the groundwater prospecting problem in the mountain area and hilly area. The successful rate is very high in well-driving.
