摘　　要：随着我国高速铁路、公路的快速发展,特长深埋隧道越来越多,如何将综合测井、地应力测试、AMT等方法准确应用于隧道工程地质勘察中,与钻探和地质测绘、原位测试、试验等相结合,对查明隧道工程地质条件、放射性强度、岩爆、地温十分重要。通过工程实例介绍地应力测试、综合测井、物探音频大地电磁(AMT)与钻探、地质调查、原位试验等相结合在特长深埋隧道勘察中应用的成功经验,对复杂地质条件特长深埋隧道勘察具有一定借签意义。With the rapid development of high-speed railway and highway in China, there are more and more super long and deep buried tunnels. How to accurately apply comprehensive logging,geostress testing, AMT and other methods to tunnel engineering geological survey, and combine them with drilling, geological mapping, in-situ testing, and testing, is very important for identifying tunnel engineering geological conditions, radioactive intensity,rockburst, and ground temperature. This paper introduces the successful experience of combining geostress testing, comprehensive logging, geophysical audio magnetotelluric(AMT) with drilling,geological survey and in-situ test in the investigation of extra long and deep buried tunnels through engineering examples, which is of certain significance for the investigation of extra long and deep buried tunnels under complex geological conditions.
