【摘要】：国民经济的增长,带动了我国跨河桥梁的建造,给周边经济与发展带来积极影响。跨河桥梁也改变了桥区的通航环境,船舶通过桥区需要面临巨大的挑战。船舶的数目增加迅速,桥区管理难度加大。桥区事故频繁发生,造成了严重的经济损失和人员伤亡。为了保障船舶的安全通航,通过对桥区的交通事故统计以及结合案例分析,得到了影响船舶通航的主要影响因素,并提出了对策:针对船舶和人为因素方面,通过分析目前船员素质、船舶安全管理等存在的不足,提出加大船舶安全检查的力度、提升船员业务素质,提高船舶的适航性。针对环境因素方面,从影响航道宽度的动态因素进行考虑,制定桥区航道优化布置设计方案。桥区航道宽度设计考虑船舶风致漂移量和流致漂移量的影响,同时桥区的浮标及航道应布置在桥墩紊流漩涡区之外。针对桥区安全管理方面,提出应加强VTS监管,合理设置桥区航标、助航标志及警戒区。本文的研究对于保障桥区安全措施方面还有不足,后续还可围绕航道、监督管理等进一步研究。
[Abstract]:The growth of national economy has led to the construction of bridge beams across rivers in China, which has brought positive influence to the surrounding economy and development. The bridge beam also changes the navigation environment of the bridge area. The number of ships increases rapidly, and the management of the bridge area becomes more difficult. Bridge area accidents occur frequently, resulting in serious economic losses and casualties. In order to ensure the safety and navigation of ships, through the traffic accident statistics in the bridge area and the analysis of cases, the main influencing factors of ship navigation are obtained, and the countermeasures are put forward: aiming at the ship and human factors, Based on the analysis of the shortcomings of the present crew quality and ship safety management, it is proposed to increase the strength of ship safety inspection, to improve the crew professional quality and to improve the seaworthiness of the ship. In view of the environmental factors, considering the dynamic factors affecting the channel width, the optimal layout design scheme of the waterway in the bridge area is formulated. The influence of wind-induced drift and flow-induced drift is considered in the design of waterway width in bridge area, and the buoy and channel should be arranged outside the turbulent vortex zone of bridge pier. In view of the safety management of bridge area, it is suggested that the supervision of VTS should be strengthened and the navigation mark, navigation aid mark and warning area of bridge area should be set up reasonably. The research in this paper is insufficient for the safety measures of the bridge area, and can be further studied around the waterway, supervision and management.
