摘　　要：为得到适用于受限航道水域船舶间安全间距确定方法,本文基于道路交通工程学的相关理论,引入船速、货种安全系数等参数构建受限航道水域船舶间安全间距计算的跟驰模型,利用该模型得到不同安全水平下,单向行驶船舶之间安全间距的表达式.以某海港进港航道两大型船舶编队进港为例,利用本文提出的船舶间安全间距确定方法从一般安全水平和充分安全水平两种情况下得到了船舶进出港安全间距值,验证了模型的科学性与有效性,为受限航道船舶间安全间距的研究提供理论依据.In order to obtain a method suitable for determining the safe distance between ships in restricted channel waters,based on the relevant theories of road traffic engineering,this paper introduces ship speed,cargo safety factor and other parameters to construct a car-following model for calculating the safe distance between ships in restricted channel waters.The model is used to obtain the expression of the safety distance between ships traveling in one direction under different safety levels.Taking a seaport’s approach channel of two large ships entering the port as an example,using the method for determining the safety distance between ships proposed in this paper,the safety distance between ships entering and leaving the port is obtained from both the general safety level and the sufficient safety level,which verifies the model’s performance The scientificity and effectiveness provide a theoretical basis for the research on the safety distance between ships in restricted waterways.
