| 摘 要： | 目前已有船舶领域模型具体取值依赖大量实测资料,缺乏理论定量研究。针对长江下游航道条件和船舶特性,基于道路交通工程中停车视距的概念,提出了航道中停船视距的概念。分析船舶制动加速度特性,探讨船舶领域模型长轴取值。研究结果表明:航道中停船视距由反应距离、制动距离以及安全距离3部分组成;当前船的制动加速度为后船的4倍时,船舶领域长轴取值为2.6~3.9倍船长,与已有进江海船的推荐值3.0~4.0倍船长基本吻合;船舶领域长轴取值具有一定的速度敏感性。

| Abstract: | At present, value-taking of existing models of ship domain depends on the measured data or
experimental data and it is lack of theory about quantitative study. According to the channel condition and ship
characteristics of the lower Yangtze River, based on the concept of stopping sight distance to traffic engineering,
we propose the concept of stopping sight distance to waterway engineering, analyze the braking accelerations of
ship, and discuss the value of major axis about ship domain. The result indicates that that ship domain to waterway
engineering is composed of reaction distance, breaking distance and safe distance. When the braking acceleration of
the ship behind is three or four times as much as the ship ahead, the value of major axis about ship domain is 2.9 to 3.8
times of the ship length. The results is basically anastigmatic with the recommended values. |
