在岩溶区修建隧道时，需要获知隧道洞线附近的地质结构，特别是要了解是否有岩溶和破碎带的发育，这些不良地质结构体对于隧道安全施工有着重要的影响。在勘查深埋长隧道不良地质体的研究中，可控源音频大地电磁法（CSAMT）是比较有效的一种方法。本文结合频率-电阻率测深曲线，将之与钻孔标本的电阻率相比较，检验原始数据的可靠性和真实性。然后对CSAMT数据进行了反演及地质解释和验证。研究结果表明，CSAMT法在岩溶区进行隧道围岩地质结构探测具有很好的效果，对于隧道施工有着一定的指导意义。

During the construction of expressway tunnel in Karst area,the geological structure near the tunnel line should be known,especially whether Karst and fractured zone develop or not,which have important influence on the safety of tunnel construction.In the geophysical exploration work on bad geologic body of deep-long tunnel, Controlled Source Audio Frequency Magnetotellurics Method (CSAMT)is fairly effective one.In this paper,we compared the original sounding curve near the borehole with the electrical resistivity of the borehole samples,to check the reliability of the data.Combination with geological interpretation and verification,the results show that CSAMT method has a good effect in exploring the geological structure of tunnel in Karst area,and has a certain guiding significance for tunnel construction.
