能见度不良条件下船舶安全尾随距离研究

Study on Ship'Safe Trailing Distance under Poor Visibility Conditions

基于船舶停车冲程和倒车冲程,运用跟驰理论,建立了船舶安全尾随距离计算模型.在船舶交通流分析的基础上,选定黄冈长江大桥桥区水域为目标水域,应用该模型计算典型船舶在目标水域的安全尾随距离.将计算结果与长江干线能见度禁航相关管理规定进行比较,认为该计算结果一定程度上可为长江干线能见度禁航标准的量化确定提供参考.

Based on the ship parking stroke and reversing stroke, the calculation model of ship safety trailing distance is established by referring to and using Ship-following Theory. On the basis of the analysis of ship traffic flow, the waters of the bridge area of Huanggang Yangtze River Bridge are selected as the target waters, and the model is used to calculate the safe trailing distance of the typical ships in the target waters. Compared the calculated results with the regulations on the control of the visibility of the Yangtze River, it is suggested that the calculation results can provide a reference for the quantification of the ban on the visibility of the Yangtze River.
