摘要
本文介绍了CSAMT(可控源音频大地电磁法 )技术在深埋隧道岩溶探测中的一个实例。为了在岩溶区得到合适的信号 ,选择了不同的发射点 ,在资料的处理中采用了空间滤波的处理方法 ,资料的解释中紧密结合地质资料及已开挖揭示的地质情况。解释结果与开挖的实际情况十分吻合 ,解决了工程施工中存在的实际问题 。
The paper introduces an application example of CSAMT technique exploring karst in deeply buried tunnel. The different distance between source and receiver was selected to guarantee enough signal strength and a spatial wave filter algorithm was used to overcome static effect. In the course of Data interpretation, the geologic data and excavation were considered especially, so the interpretation result is in accord with excavation and the problem was resolved. The application provides great enlightenment for deep karst exploration in the future.
