摘　　要：为研究北槽深水航道内慢速船驶入深水航道时对航道通航效率的影响,以交通波理论为基础,结合船舶交通流特性,建立慢速船驶入限制追越航道内的船舶交通流波动模型,解释慢速船驶入和驶出北槽深水航道前后船舶交通流的集聚和消散过程。结果表明,若慢速船在北槽深水航道非交管时间前进入,对整个航道的通航效率影响很大,需要通航管理部门制定详尽的通航计划、调配进出船顺序,以提高北槽深水航道的通航效率。To study the influences of low speed ships on the traffic efficiency in the North Deep-Water Channel, a marine traffic flow volatility model is established based on the traffic wave theory. The model, taking accounl of the entry of low speed ships into the overtaking-restricting channel, reflects the characteristics of the traffic flow, and explains the traffic flow dissipation and gathering processes in the North Deep-Water Channel due to the entry or ex- it of low speed ships. The study indicates that slow ships entering the channel during the interval of the traffic man- agement has a great impact on the traffic efficiency of North Deep-Water Channel, and it is necessary for the traffic administration to make up detailed traffic plan and control the order of entering and exiting of ships, so as to pro mote the traffic efficiency in the North Deep Water Channel.
