摘　　要：为减少边坡开挖工程量,减少施工对原地貌环境的影响,伊比利苏水电站一级引水隧洞进口边坡采用90°垂直边坡开挖的方法。钢管桩复合锚喷支护技术在水利水电工程边坡开挖中是一种新技术。该文通过该技术在伊比利苏水电站一级引水隧洞进口边坡开挖施工中的应用,对钢管桩复合锚喷技术进行介绍,积累相关施工经验,为类似工程施工提供借鉴。In order to reduce the amount of slope excavation and reduce the impact of construction on the original geomorphology environment,the entrance slope of the first-stage diversion tunnel of the Ibilisi Hydropower Station adopts a 90°vertical slope excavation method.Steel pipe pile composite bolting and shotcrete support technology is a new technology in slope excavation of water conservancy and hydropower projects.Through the application of this technology in the excavation of the entrance slope of the first-stage diversion tunnel of the Ibilisi Hydropower Station,this paper introduces the steel pipe pile composite anchorage and shotcrete technology,accumulates relevant construction experience,and provides reference for the construction of similar projects.
