摘　　要：锦屏二级水电站4条引水隧洞单洞长约16.67 km,开挖洞径12.4～13 m,最大埋深约2 525 m,受地形限制沿线无条件布置施工支洞,属典型的深埋长大隧洞。该引水隧洞工程的施工规划设计,包括高压大流量地下水处理、地应力和岩爆、超前预报、分标方案、钻爆法和TBM施工、连续带式输送系统出渣和返程带料、施工通风等技术的研究应用,将促进我国深埋长隧洞施工技术的进步。There are 4 diversion tunnels with a length of 16.67 km,excavated diameter of 12.4～13 m and maximum depth of about 2 525 m in Jinping II Hydropower Station.There is no adit for tunnel construction as the topographical constraints.During engineering planning and design,the high-pressure high-flow groundwater,stress and rock burst,forecast,tender program,drilling and blasting method and TBM construction,a continuous belt conveyor mucking system,ventilation and others are studied.The studies will improve the construction of deep-lying long tunnel in China.
