【摘要】：2014年12月25日天津港复式航道正式通航以来,依据"北进南出、双进双出"的交通流组织模式,大小船舶施行分道通航管理。但在复式航道双进双出的交通流组织模式当中,主航道内存在船舶会遇态势复杂、运营存在安全隐患的问题。本文研究旨在寻求在保障通过能力的前提下减少安全隐患的交通流组织模式。首先,本文通过收集天津港和复式航道资料,了解天津港复式航道交通流现状和航行规则,分析了该复式航道现行双进双出模式存在的安全隐患。其次,本文结合相关文献资料提出了天津港复式航道交通流组织模式的设计原则,包括安全性原则、可操作性原则以及适应性原则,并在此基础上,针对现行交通流组织模式所存在的安全隐患,提出了相关的优化方案。最后,本文针对各种交通流组织方案的安全性和可操作性进行了分析,并使用基于船舶领域理论的进港主航道通过能力计算模型,计算得出不同模式下的航道通过能力以分析其适应性。本文研究结果表明,双进双出模式下复式航道的通过能力得到了充分利用,但存在小型船舶占用主航道、主航道内交叉会遇态势复杂等安全性问题;南北航道模式可有效改善主航道内交叉会遇态势复杂以及小型船舶占用主航道的问题,但该模式下,航道通过能力存在一定程度下降;辅助航道转换模式可以改善小型船舶占用主航道的问题且在某种程度上可以提高主航道的通过能力,但存在辅助航道通过能力有所下降的问题。同时,研究结果表明,基于南北航道模式和辅助航道转换模式的天津港复式航道通过能力均可满足远期船舶进出天津港北疆港区、北港池、南疆港区的需求。本文研究结果可为有关部门完善天津港复式航道的交通流组织模式提供参考。
[Abstract]:Since December 25, 2014, Tianjin Port's dual navigation channel has been officially navigable. According to the traffic flow organization mode of "north entry and south exit, double entry and double exit", ships of big and small carry out separate traffic management. However, in the traffic flow organization mode of double-in and double-out in the dual channel, there are some problems in the main waterway, such as the complex situation of the ship and the hidden trouble in the operation. The purpose of this paper is to explore a traffic flow organization model which can reduce the potential safety risks under the premise of ensuring the passing capacity. Firstly, by collecting the data of Tianjin Port and Duplex Waterway, this paper finds out the traffic status and navigation rules of the Duplex Waterway of Tianjin Port, and analyzes the hidden danger of the current double-in and double-out mode of the Dual-type Waterway. Secondly, this paper puts forward the design principles of Tianjin Port dual waterway traffic flow organization model, including safety principle, maneuverability principle and adaptability principle. Aiming at the hidden danger of traffic flow organization mode, this paper puts forward the related optimization scheme. Finally, the security and maneuverability of various traffic flow organization schemes are analyzed, and the calculation model of the passage capacity of the main waterway based on the ship domain theory is used. The passage capacity of different modes is calculated to analyze its adaptability. The results of this paper show that the passage capacity of the double entry and double out channel has been fully utilized, but there are some safety problems such as the small ship occupying the main channel, the crossing situation in the main channel being complex and so on. The north-south waterway model can effectively improve the complex situation of crossing in the main waterway and the problem that small vessels occupy the main waterway, but under this model, the waterway passing capacity decreases to a certain extent. The auxiliary channel transfer mode can improve the problem of small ship occupying the main channel and to some extent improve the passage capacity of the main channel, but there is a problem that the transit capacity of the auxiliary channel decreases. At the same time, the research results show that the transit capacity of Tianjin Port's dual waterway based on the North-South channel model and the auxiliary waterway conversion mode can meet the needs of long-term ships entering and leaving Tianjin Port North Xinjiang Port area, North Port Pool, and South Xinjiang Port area. The results of this paper can be used as a reference for relevant departments to improve the traffic flow organization model of Tianjin Port complex waterway.
