南水北调西线工程深埋隧道地质超前预报系统研究的思考

Advance Geological Prediction System Researech Used in Deeply Buried Tunnel Project of South-to-North Transfer Water

深埋长隧道是南水北调西线工程施工中的难点,隧道地质超前地质预报可分为施工前地质预报和施工阶段地质预报,目前施工前地质预报应用的可控源音频大地电磁法及施工阶段应用的地质雷达、TSP、红外辐射测温技术有一定的效果,但是针对南水北调西线工程这样复杂的岩层,必须对现有的预报方法进行改进.

The construction of deeply buried tunnel is a difficult problem in west line project of south-to-north transfer water. Geological prediction is divided into two stages： predictions before construction and under construction. The techniques used now include CSAMT,GPR,TSP. The infrared ray are efficient in some cases. But they need to be improved in order to fit complicated rock stratum of the west line project of south-to-north water transfer.
