摘要
文章介绍了高密度电阻率法和瞬变电磁法(TEM)工作原理、特点及工作方法,并举例示范两种物探方法查找场地内溶洞及岩溶发育带的工作程序。高密度电阻率法对圈定岩溶分布、断层破碎带的追索、管线调查、物探找水、采空区、岩溶、滑坡等问题非常有效,而且成果直观、易于判读;瞬变电磁法对探测低电阻目标物敏感,主要用于探测含水层、溶洞、陷落柱、含水断层等地质构造情况。两者综合应用,可以更好地解决工程地质问题。
The paper introduces working principle and methods and the characteristics of high density resistivity and transient electromagnetic technique, and presents working procedure of the two techniques for locating karst or karst development zones in enginerring sites of the case examples. High density resistivity technique is effective for locating karst distribution, tracing cataclastic fault zones, pipeline investigation, determining underground water, mining cavities and landslide and the result is audio visual thus easy to interpret; transient electromagnetic technique is sensitive to detect targets with low resistivity, such as aquifers, karst, column collapse etc. Integration of the two techniques is more effective to solve the engineering problems.
