综合物探方法在高海拔深埋隧道勘察中的应用研究

拉萨某高海拔深埋隧道工程地形地质条件较为复杂，采用综合物探勘察方法查明隧道区地质条件。隧道区坡面表层基岩风化破碎强烈，下伏基岩主要为板岩及花岗岩；以宏观地质调绘为基础，充分发挥综合物探的解译成果，在此基础上利用钻探、试验予以验证，并通过综合分析研究，取得了良好的技术效益。

Application of Comprehensive Geophysical Prospecting and Testing Method in the Exploration of Deep Buried Tunnel at High Altitude

The comprehensive geophysical prospecting method is used to explore the geological conditions of a deep buried tunnel at high altitude built in Lhasa. The overlying stratum of the tunnel is strong weathering bedrock and the bedrock is mainly slate and granite. Based on the surveying and compiling, we can give fully play to the interpretation results of comprehensive geophysical prospecting. The results are verified by drilling and testing. Comprehensive analysis of the results show that the application of comprehensive geophysical prospecting and testing method in the exploration of deep buried tunnel at high altitude can obtain good technical and economic benefit.
