| 摘 要： | 高频大地电磁法是当前在矿产、水文、工程地质、环境等勘探领域广泛应用的物探方法。本文简要介绍了高频大地电磁测深法的基本原理、数据采集和解释技术,并结合福建省某隧道和甘肃省某隧道两个隧道的实地勘探成果,通过分析反演电阻率断面图,认为高频大地电磁法不仅能查明隧道所经地段可能存在的隐伏构造、断裂破碎带和富水区域等,还能查明地表强风化层的厚度。

| Abstract: | HMT as a geophysical prospecting method is wildly used in mining-geophysics investigation,hydrogeological investigation,engineering-geological investigation and environmental-geological investigation etc.This paper introduces the basic principle of HMT,data acquisition and interpretation techniques.HMT not only can find out the burled tectonic,fracture zone,water-bearing fracture zone but also can find out the thickness of intensely weathered zone where the tunnel ahead is considered through the profiles for HMT inversion resistivity with the exploration results from two tunnels of Fujian province and Gansu province. |
