【摘要】：随着内河航运的迅速发展,内河船舶的数量迅速增长,船舶日益大型化。内河船舶航行安全问题日益受到各界的重视。内河航运迅速发展的同时,我国城市基础设施建设速度加快,内河桥梁数量增长迅速。横跨于内河之上的桥梁数量越来越多,内河通航环境也随之发生改变,给内河船舶的航行造成了一定的限制和不利影响,桥区水域船舶碰撞事故时有发生。船舶一旦在桥区发生船撞桥事故,不仅会对内河交通造成严重影响,甚至会导致桥梁断裂等严重后果。为了更好的保障船舶在桥区水域的安全航行,研究以长江武汉段桥区水域为具体对象,针对单船在桥区的航行碰撞事故的预警方法进行了研究和探索。提出基于船舶航迹预测的桥区水域船舶航行风险预警方法,并以此为基础研发了一套船台用桥区船舶航行风险预警系统。具体研究内容如下： (1)分析长江武汉段桥区水域通航环境特征。分别从自然环境、桥梁分布情况、交通流特征三个方面进行分析,明确船舶在桥区水域航行时的主要影响因素,并得到该水域交通流特征的量化数据。 (2)桥区船舶航行风险预警方法研究。根据桥区水域通航环境特点,研究船舶航迹预测方法。并以船舶航迹预测为基础,针对碰撞、搁浅、触礁及触损四类事故风险的量化进行研究,确定桥区水域船舶航行风险预警流程和方法。 (3)桥区水域预警系统的设计与实现。以通航环境特征分析结果为基础,根据桥区船舶航行风险预警方法和流程,设计单船桥区航行预警系统,并结合AIS和长江电子航道图进行系统实现。
[Abstract]:With the rapid development of inland navigation, the number of inland ships is increasing rapidly. The problem of navigation safety of inland river ships has been paid more and more attention by all walks of life. With the rapid development of inland navigation, the construction speed of urban infrastructure and the number of inland river bridges are increasing rapidly. With the increasing number of bridges across inland rivers, the navigable environment of inland rivers has changed, which has caused certain restrictions and adverse effects on the navigation of inland water vessels. The collision accidents of ships in bridge waters occur from time to time. Once a ship collides with a bridge in the bridge area, it will not only seriously affect the inland river traffic, but also lead to serious consequences such as bridge breakage. In order to better guarantee the safe navigation of ships in the waters of the bridge area, this paper studies and explores the early warning method of the collision accident during the navigation of a single ship in the bridge area of the Yangtze River, taking the water area of Wuhan section of the Yangtze River as a specific object. A ship navigation risk early warning method based on ship track prediction is proposed and a set of ship navigation risk early warning system in bridge area is developed based on this method. The main contents are as follows: (1) the characteristics of navigable environment in the bridge area of Wuhan section of the Yangtze River are analyzed. By analyzing the natural environment, the distribution of bridges and the characteristics of traffic flow, the main factors affecting the navigation of ships in the waters of the bridge area are identified, and the quantitative data of the traffic flow characteristics in the waters are obtained. (2) study on ship navigation risk warning method in bridge area. According to the characteristics of navigation environment in the bridge area, the ship track prediction method is studied. On the basis of ship track prediction, the paper studies the quantitative risk of collision, grounding, reef and touch loss, and determines the warning process and method of ship navigation risk in the waters of bridge area. (3) the design and implementation of water area early warning system in bridge area. Based on the results of navigation environment analysis and according to the method and process of ship navigation risk early warning in bridge area, the navigation early warning system of single ship bridge area is designed, and the system is realized by combining AIS and Yangtze River electronic waterway map.
