随着我国水电建设的发展，大跨度导流洞在水电工程中越来越多，其中埋藏较浅的大跨度导流洞进口渐变段存在着较大安全隐患。本文以糯扎渡水电站2号导流洞为例，对该部位的开挖支护设计与施工方案进行了研究，对类似工程具有重要的参考和借鉴价值。

Large span diversion tunnel is more and more applied in hydropower projects with the development of hydropower construction in China,wherein shallow embedded large-span diversion tunnel reducing section has larger safety hidden danger.In the paper,Nuozhadu Hydropower Station No.2 diversion tunnel is adopted as an example for studying excavation support design and construction plan in the part,thereby it has important reference value for similar projects.
