【摘要】：航道的交叉是一种在海上和内河中较为常见的现象,虽然IMO及各参与国针对该种现象制订了较为详细的航行规则,但船舶在航道交叉水域发生碰撞的事故在逐年上升。其原因除了全球船舶数量的不断增加,航行区域不断的扩大,通航能力不断的接近饱和以及航线的过度开辟等因素外,船员的素质,交叉航道的特征和所处环境的变化以及船舶的性能等也是重要的影响因素。因此对如何降低航道交叉处船舶通过时的风险进行研究,减少航道交叉水域的碰撞事故的发生,具有重要的现实意义。本文首先对海上及内河的三类常见交叉航道进行系统的分析,对影响通航安全的因素进行归类,通过模糊数学、矩阵、概率等一些数学手段进行模拟,得出各类影响因素的等级,并提出一些较为切实可行的改进措施和方案。其次,针对最为常见的内河Y型交叉航道进行研究,通过模拟得出水流回流区对该航道的危险影响状况,并提出改进方案。
[Abstract]:The crossing of waterways is a more common phenomenon at sea and inland waters, although the IMO and participating States have developed more detailed navigation rules for this phenomenon. However, the accidents of ships colliding in waterway crossing waters are on the rise year by year. Besides the increasing number of ships in the world, the expansion of navigation areas, the constant saturation of navigable capacity and the over-opening of routes, etc. The quality of the crew, the characteristics of the crossing channel and the change of the environment, as well as the performance of the ship are also important factors. It is of great practical significance to reduce collision accidents in waterway crossing waters. Firstly, this paper makes a systematic analysis of three common cross waterways at sea and inland rivers, classifies the factors that affect navigation safety, and classifies them by fuzzy mathematics. Some mathematical methods, such as matrix, probability and so on, are simulated to get the grade of all kinds of influencing factors, and some more feasible improvement measures and schemes are put forward. Secondly, the most common river Y crossing channel is studied. The dangerous influence of the flow return zone on the channel is obtained by simulation, and an improved scheme is put forward.
