摘要： 乌江属典型的山区峡谷型弯曲河道,洪峰量大、变幅大、设计水头高,使得通航建筑物的平面布置难度大,引航道口门区的通航条件较为复杂。以乌江主要枢纽为原型,建立峡谷型弯曲河道枢纽通航建筑物概化模型,研究不同引航道布置方式、尾水渠与下游河道的交汇角度对下游引航道口门区通航条件的影响程度,提出适宜的布置方式。

关键词: 峡谷型弯曲河道, 通航建筑物, 水流条件

Abstract: There are many aspects which seriously influence the navigation condition in the entrance area of approach guide channel especially at downstream of hydropower plant of Wujiang River,such as higher head of water,large discharge,and narrow and bent river valley.Taking the hinge of Wujiang River as the prototype,the model of hydro-complex in narrow reach with bend in valley is established.The layout of different approach channels,the influence of guide channel and the skew angle of tail water channel on the navigation condition in the entrance area of lower river are studied.The principle in general configuration of the navigation building with hydrodynamic building is proposed.

Key words: narrow reach with bend in valley, navigation building, flow condition
