摘要
官地水电站右岸导流洞进口渐变段属特大型洞室。结合进口渐变段不良地质段的施工情况,围绕恶劣地质条件下特大断面洞室开挖支护、塌方处理、隧洞混凝土衬砌等方面的施工技术进行了总结。
Transition section in intake of diversion tunnel at left bank of Guandi hydropower station is an extra large cavern.Considering construction conditions in unfavorable geologic section in intake transition section,this paper presents a summary of construction technology for extra large cavern excavation and support,rock falling treatment and tunnel concrete lining under poor geologic conditions.
