中文摘要:
      狗头湾滩段作为汉江中下游重要的通航河段,在丹江口水库和引江济汉调水工程实施后,其上游来水历时、流量均发生巨大变化,水流、泥沙运动和河床变化十分复杂。结合近年实测河道水文、地形资料以及模型试验资料研究狗头湾整治方案,重点分析了该段浅滩的演变特征、水流与泥沙的运动关系以及碍航特性,提出整治工程方案。验证结果表明,整治工程的实施稳定了工程河段洲滩,束窄了中、枯水河宽,深槽普遍冲刷且走向稳定,中、枯水河势得以有效控制和巩固。研究成果可为狗头湾段浅滩和相似河道整治提供参考依据。
英文摘要:
      As an important navigable reach of the middle and lower reaches of Hanjiang River,after the implementation of Danjiangkou Reservoir and the Yangtze River to Hanjiang River water diversion project,the upstream water duration and discharge have undergone great changes,and the changes of water flow,sediment movement and riverbed are very complicated.This paper studies the regulation plan of Goutou Bay based on the measured hydrology,topographic data in recent years and model test data,it focuses on the analysis of the evolution characteristics of the shoal section,the relationship between water flow and sediment movement and the characteristics of navigation-obstructing and proposes the regulation project.The verification results show that the implementation of the regulation project stabilizes the project reach beach,narrows the width of the middle and low water river,the deep trough is generally scoured and tends to be stable,and the middle and low water river regime can be effectively controlled and consolidated.The research results can provide reference channel regulation of Goutou Bay section shoal and similar channel section.
