CSAMT法在高黎贡山隧道方案评价中的应用分析

结合高黎贡山隧道可控源音频大地电磁法的应用实例，详细论证了这种方法在隧道方案比选中的应用。通过物探资料对三个方案隧道的地层岩性、地质构造，特别是对深大活动断裂的分布位置、破碎带宽度及隧道围岩的完整程度作了详尽的分析和解释，并对物探判释的隧道洞身穿越断层破碎带、物探Ⅴ类异常（极破碎或富水岩体）和物探Ⅳ类异常（破碎或含水岩体）的长度进行了统计，从物探的角度对三个隧道方案进行了评价，为隧道的方案比选提供物探基础资料。

The Application of CSAMT Method in the Program Evaluation of Gaoligongshan Tunnel

Based on the application of controlled source audio-frequency electromagnetic method to GAOLIGONGSHAN tunnel,this paper is about to talk about the applications of this method in the tunnel and it is a much better way of all.Through the geophysical data,it,in details,analyzes and interprets the formation lithology,geological structure,especially the location of the deep active fault,the width of broken rock and the integrity of the tunnel of the three programs,but also the length of the fault zone of the tun...
