摘要
金安桥水电站导流隧洞渐变段在国内属于较大规模的洞挖渐变段,而且设计为平顶形式,应为国内最大跨度的洞挖平顶渐变段。本文通过对金安桥水电站导流洞进口渐变段大断面平顶洞室开挖、支护施工技术的总结,旨在对今后类似工程起到借鉴作用。
Jin＇an bridge hydropower station diversion tunnel transition section belongs to large-scale cavity digging transition section.And the design is flat-topped form which is the biggest domestic cavity digging flat-topped transition section.The paper summarized the digging and supporting construction technology of Jian＇an bridge hydropower station diversion tunnel transition to provide some reference for future＇s similar projects.
