某新建铁路复杂长隧道岩层地质与CSAMT特征
|
摘要
分析了多种地球物理勘探方法在复杂长隧道探测中的优缺点,指出了CSAMT(可控源音频大地电磁)法在工作条件极其困难,地形复杂,交通不便,要求勘探深度大的隧洞勘察中,是一种行之有效的物探手段.以较高的显示度列举了CSAMT法在本区探测成功的实例.就隧道主要特殊岩层膏溶角砾岩的地球物理异常特征进行了详尽分析,给出了CSAMT法在本区隧道结构面综合地质解释结果.
This paper analyses the advantages and disadvantages of many geophysical exploration methods which are used in long complex railway tunnel,and points out that CSAMT(Control Source Audio-frequency Magnetotelluric Method) is a powerful exploration method of applied geophysics for deeper and complex geology structure exploration.The paper shows some successful examples of CSAMT survey in the area studied.The resistivity anomalies for the typical geology layer of gypsum breccia in this railway tunnel are particularly analyzed,and the integrated interpretation results for CSAMT survey conducted for the tunnel is illustrated.
