摘　　要：CSAMT法是一套综合了MT和AMT各自优点的电磁自动采集和处理系统。文章介绍了CSAMT的原理、特点、工作方法和资料处理。该系统首次运用于水麻高速公路深埋隧道勘察中,结合其它手段,成功地解译出了隧道的软弱层、地下水及断层破碎带的位置,为划分隧道围岩类别提供了较好的依据,同时也为高速公路深埋隧道提供了一种新的勘察方法。CSAMT is an electromagnetic automatic data collecting and analyzing system which comprises the ad- vantages of MT and AMT. The paper introduces the principle, characteristics, working methodology and data processing of CSAMT based on its application in the survey and investigation of a deeply - embedded tunnel on an ex- pressway in Yunnan. CSAMT successfully interpreted the location of soft and weak layers, the location of underground water and fracture zones with the assistance of other technical approaches, which provided a good basis for classifying the surrounding rocks of the tunnel and a new approach for the surveying and investigation of deeply - embedded highway tunnels,
