摘　　要：本文阐述和分析了糯扎渡水电站右岸泄洪洞有压段大直径圆形断面混凝土衬砌及无压段大尺寸城门洞形混凝土施工技术模板选型,对比分析出底板滑模、翻转模板、组合大钢模、钢模台车、移动钢管排架模板支撑等施工方案优点,总结了大流量、高流速、结构复杂的特大型水工隧洞混凝土模板施工方案,旨在供今后同类工程施工借鉴。The concrete hning for the large diameter pressure circular section of the flood discharge tunnel on right bank of Nuozhadu Hydropower Station and the concrete construction technology for the large sized non-pressure horseshoe section of the tunnel are expatiated and analyzed herein ; in which the merits of the construction schemes such as slip-form construction of bot- tom-slab, turn-over formwork, large composite steel formwork, steel-formwork jumbo, movable formwork steel-pipe scaffold supporting, etc. are comparatively analyzed, while the schemes for the concrete formwork construction of the super-large hydrau- lic tunnel with large flow rate, high flow velocity and complicated structure are summarized as well, so as to provide references for the similar projects in the days to come.
