CSAMT结合高密度电阻率法在铁路深埋隧道勘探中的应用

Application in railway tunnels deep exploration of the CSAMT combined high density resistivity method

在铁路深埋隧道工程地质勘察中,采用CSAMT法结合高密度电阻率法勘探组合。高密度电阻率法弥补了CSAMT法对浅部分层上的不足,同样CSAMT法又弥补了高密度电阻率法在勘探深度上的不足。当在接地良好、电磁干扰较小的地质环境条件下,两种方法都可以划分层面,用两种方法相互验证,得到的结果更接近实际情况。通过实例证明此种组合是一种行之有效的勘探方法。

In railway engineering geological exploration in deep tunnel,a combination of CSAMT high density resistivity method prospecting combinations is used.High density resistivity method to make up for lack of CSAMT shallow portions of the layer,the same,CSAMT up for the lack of high-density resistivity method in the exploration depth.When there is a good grounding,electromagnetic interference smaller geological environment,both methods can be divided into levels,there are two ways to authenticate each other,and the result is closer to the actual situation.This paper describes examples of the kinds of combinations of process application in practice to demonstrate that this combination is an effective exploration method.
