引江济汉通航工程进口段平面布置及通航条件优化

用水流物理模型、遥控自航船模、水流数学模型和船舶操纵运动数学模型相结合的研究方法对引江济汉通航工程进口段平面布置及通航条件进行研究。首先阐述设计方案通航工程与长江交汇口、进口龙洲垸船闸下游航道及荆江大堤通航孔等各区域的通航条件,详细分析设计方案影响通航水流条件的各个因素,针对设计方案在通航水流条件上的不足,通过采取多种工程措施改善其通航水流条件,提出满足船舶安全航行的优化布置方案。

Optimization of plan layout and navigable condition in water diversion project from the Yangtze River to the Hanjiang River

The plan layout and navigable condition in the water diversion project from the Yangtze River to the Hanjiang River are analyzed by a combination of the tidal current physical model test, remote-control selfpropulsive ship model, mathematical model and maneuvering mathematical model. This paper expounds the navigation condition of the junction of the Yangtze River and the water diversion project, downstream channel of Longzhouyuan lock and navigable spans of Jingjiang dyke, analyzes the influential factors of the navigable flow condition in the design, and proposes the optimal layout scheme which satisfies the requirement of safe navigation through taking a variety of engineering measures to improve the navigable floe condition to counter the disadvantages of the design scheme.
