Abstract: The regulation project of the water level of Shuikou Dam of Minjiang River, in Fujian was built to solve the problems of river bed cutting down, water level lowering and inadequate navigation depth in the lower reaches of Shuikou Hydropower Station. The main buildings of the hub were backwater weir and retaining dam, ship lock, and the left bank slope protection, etc. In the engineering design, aiming at raising the downstream water level, improving navigation conditions and other issues, a multi-program model test was carried out. The experiment results show that the adjustment sections of upstream and downstream approaches can effectively improve the navigation flow condition and meet the operation requirements by adding the solid guide wall and waterproof board; the navigation flow condition of the anchor section of upstream approach can also be improved by appropriately extending the navigation wall combined with comprehensive measures, such as void isolating wall. This article is a brief introduction to the research on the navigation conditions of the hub.

Key words: waterway engineering, hydraulic model experiments, navigation technology of the hub, navigation condition of the flow, the entrance area of the approches

摘要: 福建闽江水口坝下水位治理工程,是为了解决水口水电站下游河床下切、水位下降、通航水深不足而兴建的,枢纽主要建筑物由壅水堰、挡水坝、船闸及 左岸护坡等组成。在工程设计中围绕抬高下游水位、改善通航条件等问题,开展了多方案模型试验研究。试验成果表明:上、下游引航道调顺段通过增加实体导 墙和隔水板的措施,上游引航道停泊段通过适当延长导航墙并结合透空隔流墙等综合措施,可有效改善通航水流条件,满足运行要求。本文将简要介绍该枢纽通 航条件试验研究情况。
