摘要/Abstract

摘要： 对收集的资料进行整理分析,以干支流交汇角为变量概化成三个模型,在交汇角为30°、60°、90°时,分15组流量对交汇河段的水面形态特征进行了试验研究,同时在交汇口布置挑流坝观测其水位变化.研究结果表明:汇流比R_Q和交汇角α对交汇河口的水面形态特征起控制作用.R_Q一定,不同的干流流量(Q_干)直接关系到交汇河口的水面特征,布置挑流坝改变了两江交汇角,必将引起汇口水面特征的改变.

关键词: 交汇河口, 交汇角, 汇流比, 水流特性

Abstract: In this paper, collected information has been analysed.Then, regarded the confluence angle as variable, we summarize them into three models with the angles of 30°、60°、90°.Experimental study has been proformed about the water surface characteristics with fifteen discharge combination, and building dam at the junction has also been tested.Results indicate that the discharge ratio of two tributaries upstream and the confluence angle decide the water pattern characteristics at the junction.When the discharge ratio is given, the main canal discharge is related to the water characteristics directly at the junction.in fact, building dam reduces the angle, and it must change the appearance at the junction.

Key words: junction, confluence angle, discharge ratio, water characteristics
