【摘要】：天津港三港池泊位码头改造后,泊位所停靠船舶尺度将加大,同时也增加了三港池海域的通航风险,对附近海域通航环境产生较大的影响。为避免通航环境恶化,保障船舶航行安全,防止海域污染,系统科学地对三港池泊位码头改造工程通航安全研究非常重要和必要。论文结论不仅能为制定工程的安全生产提供对策,为海上安全监管提供科学依据,还能够保障和促进通航水域的可持续发展。本文首先介绍了天津港三港池泊位码头改造工程概况,分析总结了码头改造所在海域的分析气象、水文等自然环境；分析总结港口、航道等港口基础设施情况；选取了海域的三种代表船型,统计了船舶交通流特征和航迹分布特点；分类统计了该海域近十年的交通事故；分析了通航安全监管机构和救助力量分布,结果表明该海域通航的自然环境较为简单。在此基础上,论文从合理性、码头改造设计要素规范性、码头靠泊能力适应性和船型发展一致性等方面研究了天津港三港池泊位码头改造的可行性,计算了港池宽度、码头前沿高程、泊位长度、前沿停泊水域宽度和水深、港池及回旋水域水深和直径、制动水域的长度、船舶系缆力和码头防撞力等要素,结果表明海域实际情况满足设计要求分析了天津港三港池泊位码头改造对通航环境的影响。论文研究了码头改造与自然环境影响的相互影响,分析了码头改造后船舶进出港、靠离泊方式及其对附近船舶交通流、航道通过能力的相互影响,分析被改造泊位之间的相互影响,以及对附近泊位影响分析,并给出了相关建议。论文结合专家指导和问卷调查,利用层次分析法,识别了改造工程影响通航安全的风险因子,建立了通航安全评价指标体系,分析各风险因子对通航安全的影响程度。利用综合安全评价模型,分析评价了三港池的通航安全等级,结果为较低危险,并提出了控制风险的缓解措施。本文的研究为科学评价天津港三港池泊位码头改造对通航安全的影响提供了参考。
[Abstract]:After the transformation of the berth terminal of the three ponds of Tianjin Port, the ship size of berth will be enlarged, and the navigable risk in the sea area of the three ports will also be increased, which will have a great impact on the navigation environment of the nearby sea area. In order to avoid the deterioration of navigable environment, to ensure the safety of navigation and to prevent sea pollution, it is very important and necessary to systematically and scientifically study the navigable safety of the modification project of berth wharf in three ports. The conclusion of this paper can not only provide the countermeasure for making engineering safety production, provide scientific basis for maritime safety supervision, but also guarantee and promote the sustainable development of navigable waters. Firstly, this paper introduces the general situation of the reconstruction project of the berth of the third port of Tianjin Port, analyzes and summarizes the natural environment such as meteorology, hydrology, and so on, analyzes and sums up the basic facilities of the ports, such as ports and waterways, etc. Three representative ship types in the sea area are selected, the characteristics of ship traffic flow and track distribution are counted, traffic accidents in the sea area in the past ten years are classified, and the distribution of navigable safety supervision agencies and rescue forces is analyzed. The results show that the natural environment of navigation in this area is relatively simple. On this basis, this paper studies the feasibility of reconstructing the berth wharf of Tianjin Port from the aspects of rationality, standardization of design elements of wharf reconstruction, adaptability of berthing capacity and consistency of ship type development, and calculates the width of Port Pool. Berth length, berth width and depth, water depth and diameter of ponds and roundabout waters, length of braking waters, ship mooring force and wharf collision resistance, etc. The results show that the actual situation of the sea area meets the design requirements and analyzes the influence of the transformation of the berth terminal of the three ponds of Tianjin Port on the navigable environment. The paper studies the mutual influence of the wharf reconstruction and the natural environment, and analyzes the interrelation between the ship entering and leaving the port after the wharf transformation, the way of berthing, and its influence on the traffic flow of the nearby ship and the passage capacity of the waterway. The interaction between the modified berths and the influence on the nearby berths are analyzed, and the relevant suggestions are given. Combined with expert guidance and questionnaire investigation, the paper identifies the risk factors that affect navigable safety in revamping engineering, establishes the evaluation index system of navigable safety, and analyzes the influence degree of each risk factor on navigable safety. By using the comprehensive safety evaluation model, the navigable safety grade of the three port ponds is analyzed and evaluated. The results show that the risk is lower, and the risk mitigation measures are put forward. The research in this paper provides a reference for the scientific evaluation of the impact on navigation safety caused by the transformation of the berth of the third port of Tianjin Port.
