| 摘 要： | 乐滩水库引水灌区一期工程隧洞12座,总长为48.77 km,均为无压隧洞,针对隧洞从村屯附近穿越、长距离、低水头、大流量的特点,设计有针对性地提出了一些新观点。结合工程实际,从洞线选择、进出口布置、合理加大隧洞水深、减糙衬砌混凝土使用、TBM法施工应用等简述其设计要点。

| Abstract: | Letan Reservoir Irrigation Zone 1st stage Project is designed with 12 free-flow tunnels with a total length of 48.77km. Some new design concepts were put forward in view of the features of tunnels such as passing nearby villages, long distance, low water head and high flow. A brief introduction was made on the key points of design in respects of tunnel line selection, arrangement of tunnel inlet and outlet, rational increase of water depth in tunnel, application of less rough concrete lining and TBM construction method. |
