瞬变电磁法在变电站地质物探中的应用
摘要
在电力系统地质探测方面
为了查明引发滑坡的地质形态特征
简要介绍了瞬变电磁法(TEM)的工作原理及其探测方法
并以滇东北区某变电站周边边坡进行探测为例
通过对视电阻率成像图进行分析
得到了视深断面图的地形特征
总结了地质形态的分布情况。与传统的电阻率法相比
瞬变电磁法能够高效、简便地运用在山地环境的地质物探中。
Abstract
In power system geological survey
in order to find out geological characteristics of landslide
briefly introduce working principle of transient electromagnetic method( TEM) and its detecting method
taking a substation in the northeast of Yunnan Province as an example
by analysis on apparent resistivity imaging map
topographic features of apparent deep cross section are obtained
and the distribution of the geological forms is summarized. Compared with traditional resistivity method
transient electromagnetic method can be used in geological environment of the geophysical exploration.
