摘要
Abstract
In the construction process of hydropower projects,excavation and support of hydraulic tunnel open-ings are usually the focus and difficulty of construction control.When encountering situations where the super large section hydraulic tunnel openings are set in unfavorable geological zones,there will be greater uncertainty and hidden dangers in the safety,quality,and progress control of excavation and support construction.Based on the the measures taken during the excavation and support construction process of a diversion tunnel portal of a hydropower project in the Dadu River Basin,this paper expounds exploration on the construction measures for excavation and support of super large section hydraulic tunnel portal under adverse geological condition in order to provide reference for similar projects under unfavorable geological conditions.关键词
