【摘要】：随着港口设施建设的不断完善和扩建,尤其是超大型船舶码头的建成投产,越来越多的超大型船舶将会涌入现有的航道,致使水上交通环境日趋拥挤和复杂。为了充分发挥港口的作业能力,保持船舶航行和作业安全,提高通航效率,研究航道通过能力以及超大型船舶通航对交通流及航道通过能力的影响是非常必要的。超大型船舶的船舶领域、操纵性能以及航行行为与一般船舶不同,势必会对海上航道的通过能力产生影响。船舶交通系统,尤其是跟港口、泊位、锚地结合在一起时,整个系统环境十分复杂,受到多种条件的制约,采用传统的数学分析方法来计算航道的通过能力往往不能考虑到这些复杂的条件,因此计算得到的结果与实际的航道通过能力有很大偏差。随着计算机技术的发展,计算机仿真技术被越来越多的学者应用到航道通过能力的计算与评价当中。本文通过对现有文献资料的收集整理,分析了现有对航道通过能力的研究成果,对超大型船舶的尺度及操纵特点进行了分析,并对交通流理论以及船舶交通仿真进行了分析。同时借鉴以往的研究成果,建立超大型船舶通航对航道通过能力影响的定性、定量分析方法,该方法可以协助有关部门评价航道在不同交通条件下的通过能力。本文首先对超大型船舶进行尺度界定,以仿真船舶为研究对象,并结合海上专业实践经验,建立有超大型船舶参与的交通流模型,并确定通航安全及通航效率的评价指标,通过定性与定量相结合的方法,研究超大型船舶通航对航道通过能力的影响,并提出提高通过能力的建议。
[Abstract]:With the continuous improvement and expansion of the construction of port facilities, especially the completion and production of the super large ship wharf, more and more super large vessels will be flooded into the existing waterways, resulting in the increasing congestion and complexity of the water traffic environment. In order to give full play to the operation capacity of the port, maintain the safety of navigation and operation of the ship, and improve the efficiency of navigation, The passage capacity of the channel and the influence of the navigation of the super large ship on the capacity of the traffic flow and the channel are very necessary. The field, the maneuverability and the navigation behavior of the super large ship are different from those of the general ship. It is bound to have an influence on the passing capacity of the sea channel. The ship pass system, especially with the port, berth and anchorage At the same time, the whole system environment is very complex and is restricted by many conditions. The traditional mathematical analysis method is often used to calculate the passage ability of the channel. So the calculated results are very bad with the actual channel passing ability. With the development of computer technology, computer simulation is used. More and more scholars have been applied to the calculation and evaluation of the ability of channel passage. By collecting and sorting out the existing documents, this paper analyzes the existing research results of the passage capacity of the channel, analyzes the scale and manipulation characteristics of the super large ships, and divides the traffic flow theory and the ship traffic simulation. At the same time, drawing on the previous research results, the qualitative and quantitative analysis method of the influence of the super large ship navigation on the passage capacity is established. This method can assist the relevant departments to evaluate the passage ability of the channel under different traffic conditions. First, the scale is defined to simulate the ship as the research object and the sea is combined with the sea. On the basis of professional practice experience, a traffic flow model with the participation of super large ships is established, and the evaluation index of navigation safety and navigation efficiency is determined. Through the combination of qualitative and quantitative methods, the influence of the navigation on the passage capacity of the super large ship is studied, and the suggestion of improving the capacity is put forward.
