摘要
以多年实测资料为基础,从河段水流动力条件和河床演变分析着手,结合三峡工程的影响,对安庆河段的河势进行研究。该河段河道演变特点为:洪水河势基本稳定;新河口边滩生成后以小幅冲淤变化为主;鹅眉洲与潜洲此消彼长;新中汊的演变与新河口边滩、鹅眉洲和潜洲的变化密切相关。结合航道整治工程的实施,对安庆河段河床演变的趋势进行预测。
Based on the annual survey data, this paper analyzes the dydro-dynamic condition and bed evolution process, and researches the river regime of Anqing reach. The characteristics of river bed evolution are as follows: the flood river regime is stable; the Xinhekou point bar is basically stable with slight deposition and erosion; the process of new middle channel is closely related to Xinhekou point bar, Emei sandbar and Qian sandbar. Combining with the implementation of waterway regulation, the fluvial tendency of Anqing reach is predicted.
