摘　　要：针对长江中游熊城段碍航水流问题,采用数学模型对该河段水流特性进行研究。结果表明:因河道弯曲狭窄、洲滩不高,且受洞庭湖出流影响,熊城段水流三维特性明显,存在横流、环流、回流等多种水流结构,对船舶航行影响大;在干线来流量2.5万~3.0万m3/s且洞庭湖水位偏高时,易发生船舶事故,应提醒船舶谨慎航行。Aiming at the problem of navigation-obstructing flow in Xiongcheng reach of the middle Yangtze River,we use a mathematical model to study the flow characteristics of the reach.The results show that the riverway is narrow and curved,the beach is not high,and affected by the outflow of Dongting Lake,the three-dimensional characteristics of flow in Xiongcheng reach are obvious,and there are many flow structures such as crossflow,circulation and backflow,which have great influence on ship navigation.When the flow of the trunk line is 25,000 m 3 s to 30,000 m 3 s,and the water level of Dongting Lake is high,ship accidents are likely to occur,so it is necessary to remind ships to navigate with caution.
