摘要
向家坝水电站灌区工程南北总干渠首部取水隧洞工程是向家坝水电站后期灌溉工程的重要组成部分,地质条件复杂、施工难度大。分别介绍了不同围岩类别和不良地质洞段开挖与支护实施程序、方法、工艺及实施效果,可为类似工程提供参考。
The diversion tunnel of north and south main irrigation canals is an important part of irrigation project in Xiangjiaba Hydropower Station. As complex geological conditions, the construction of tunnel is difficult. The tunnel is excavated by NATM. The excavation and supporting procedures, methods, processes and results of tunnel sections with different surrounding rock are introduced. The excavation and supporting of tunnel can be as references for similar projects.
