大藤峡水利枢纽船闸上引航道口门区水流条件模型试验

摘要

建立大藤峡水利枢纽水工整体物理模型,对大藤峡水利枢纽船闸上游口门区布置方案进行试验验证,结合上游引航道口门区布置及附近地形分析,对工程方案进行优化,通过调整引航道中心线制动段弯道弧度和半径、 调整口门区与上游主航道连接形式、 增设导航墩和优化口门区附近区域地面高程等工程措施,使口门区的水流条件满足通航要求,并节省工程量.%We establish the physical model of Datengxia water conservancy project, verify the layout scheme of the upper entrance gate of Datengxia water conservancy project experimentally, and use the layout of the entrance channel of the upstream approach channel and the analysis of nearby terrain to optimize the engineering scheme.By adjusting the curvature and radius of the center line braking section, changing the connection form between the entrance gate and the upstream main channel, increasing the navigation piers and optimizing the ground elevation in the vicinity of the entrance area, etc., the flow condition in the entrance area can meet the navigation requirements. The engineering quantity can be saved.
