钻孔电磁波层析成像技术的应用效果

Applying Effect of Drilling Electromagnetic Wave Tomography

电磁波层析成像是在电磁波法基础上发展起来的一种高分辨地球物理勘探手段,以获得孔间电磁吸收系数或电导率分布图像为主要工作内容,从而达到探明孔间物性分布、确定异常区之目的。本文简要介绍了钻孔电磁波层析成像技术基本的方法原理,通过实例,描述了其在岩溶工程勘察中的作用和较好的应用效果。

Electromagnetic wave tomography that is a high-resolution geophysical exploration method is developd on the basis of electromagnetic wave.In order to ascertain the physical distribution and abnormal area between the holes through gaining the electromagnetic absorption coefficient or conductivity distribution image.This article briefly introduces the basic principle of Drilling Electromagnetic wave Tomography technology,and describes its function and application effect in the engineering investigations in the karst.
