| 摘 要： | 为减小截流难度,通过模型试验对西藏藏木水电工程导流明渠截流戗堤轴线进行了研究和优化.摒弃传统的戗堤轴线垂直或近似垂直于明渠主流的设计理念,采用折线形戗堤轴线,将原主流向截流变为侧向截流,并充分利用残留的二期上游围堰和明渠进口右边墙,将截流戗堤龙口设置于导流明渠进口右边墙内侧河道内.优化戗堤轴线达到了降低龙口各项水力学指标、明显减轻明渠截流难度的目的.

| Abstract: | In order to reduce the difficulty of closure,the diversion channel closure dike axis of Zang-mu Hydropower project in Tibet is stuelied and optimized through model test.The traditional design conception which dike axis is vertical(or approximately vertical) to mainstream is not adopted,but in this case,the polyline dike axis is used.At the same time,main-flow closure is abandoned and lateral closure is adopted.Besides,taking full advantage of the remnant upstream pre-cofferdam and the right wall of channel ... |
