汉江雅口枢纽厂坝间上游导墙布置试验研究

Research on layout of upstream guide wall between dam and plant of Yakou hydro-junction

内河航运枢纽厂坝间上游导墙布置参数与电站运行及枢纽泄洪密切相关。针对汉江雅口航运枢纽,采用物理模型试验研究了厂坝间导墙长度以及墙身开孔对电站进流和枢纽泄流能力的影响。结果表明,在设计拟定的三种导墙布置长度下,导墙长度越短对枢纽泄流能力及电站进流条件影响越小,同时导墙开孔可进一步提高泄流能力和改善电站引流条件。

In inland navigation, the layout parameters of upstream guide wall between dam and plant of hydro-junction are closely related to the operation of the power station and the flood discharge of the hydro-junction. Based on the physical model test of Yakou hydro-junction, the influences of guide wall length and opening of guide wall on the inlet of power station and the discharge capacity of hydro-junction were studied. The results show that under the design of thine kinds of guide wall layout length, the shorter the length of the guide wall is, the smaller the influence on the discharge capacity of hydro-junction and the water inlet condition of the power station. Meanwhile, the opening of the guide wall can further improve the discharge capacity and the drainage conditions of the power station.
