摘　　要：西藏旁多水利枢纽截流施工具有高海拔、一次截流、隧洞导流、河床抗冲能力差等特点,通过1:60比尺的模型试验,提出采用部分龙口段平抛护底、右岸预留裹头的截流方案,平顺了合龙前龙口流态,提高河床抗冲刷能力,节省了抛投量。该截流布置型式对于其他水利工程截流方案设计具有一定的借鉴意义。Tibet Pangduo water conservancy construction closure has the characteristics of high altitude ,dis-posable closure,diversion tunnel,poor riverbed erosion.By 1：60 scale model test,using bottom protection on parts of river channel,on the right bank set aside wrapped head,the flow pattern was smoothed before the river channel closing,which improved the ability of anti-erosion riverbed,and savings dumped.The closure arrange-ment type design has a certain significance for other water closure plan.
