【摘要】 尹公洲航段具有弯曲、狭窄、船舶流量大、多分汊河口、水流流态紊乱等特点,决定了整个长江下游船舶的通过能力和航行效率,制约了大型船舶安全通过尹公洲航段,成为限制长江航运发展的“瓶颈航段”。一旦发生重大水上交通事故,可能造成航道阻塞,使长江和京杭运河的航运在镇江段被迫中断,造成十分严重的经济损失和社会影响。为适应当前航运发展的需要,科学地利用尹公洲航段的通航条件,有必要对长江尹公洲航段的通航环境与单船通航能力通过进行科学论证,为海事管理部门对大型单船通过尹公洲航段提供科学监管依据。本课题主要是通过对尹公洲航段气象条件、水文条件和航道条件的分析,结合航道的实际特点,建立船舶航行漂移量的数学模型,从理论上计算出尹公洲航段可通过单船的最大尺度,并应用船舶模拟仿真的方法,与理论计算结果相对比,从而验证改研究成果具有实践性和普遍性。本课题共分为五个部分:一、概述:主要介绍课题的来源与背景、国内外研究现状、研究的目标、内容和拟解决的关键问题,明确课题研究的方向和总体思路。二、影响航道通过能力的要素分析:对尹公洲航段的气象条件、水文条件、航道条件和主要通过船舶的类型和尺度进行分析,为建立船舶航行漂移量数学模型和船舶航迹带宽度计算提供数据依据。三、航道通过能力数学模型的建立:根据尹公洲航段的实际特点,建立顺直航道和弯曲航道船舶漂移量的数学模型,分别计算出不同水位期航道有效宽度和航道水深对船舶通过能力的限制。四、船舶仿真模拟研究:通过不同典型船舶通过尹公洲航段的仿真模拟研究,在不同的外界条件下试验得到尹公洲航段限制通航的船舶尺度,与理论计算结果进行对比分析研究,验证该研究成果具有实践应用价值。五、研究结论:通过理论计算与仿真模拟研究的成果,综合分析船舶在各种因素的作用下,尹公洲航段可通过的典型海船的最大长度、宽度、吃水及相应的安全措施。更多还原

【Abstract】 YinGongZhou channel is characterized by its curving, narrow, large traffic flow, multi-branching estuaries and disordered state, which not only decides Yangtze River’s traffic capacity and navigational efficiency , but also restricts the safety passing of large-vessels,and becomes "bottleneck channel" of restricting the development of Yangtze River shipping industry. Once serious traffic accident happens, it may result in obstruction and interrupt the shipping of Yangtze River and Beijing-Hangzhou canal in ZhenJiang, causing serious economic losses and social impacts.In order to meet the need of the development of present shipping industry and make use of YinGongZhou Channel’s navigation condition scientifically, it is necessary to carry on scientific research about navigation condition and single ship traffic capacity to provide scientific supervision basis for maritime administration departments about large single ships crossing the channel.This paper aims to establish a mathematical model of ship navigation drift by analysis of meteorological condition, hydrology condition and the channel’ condition, together with the channel’s actual characterics. Finally we calculate the largest single ship crossing the channel and confirm the practicality and universality of the research result by the ship simulation method and compassion with theoretical calculation results.This thesis is composes of five parts:1.Summary: introduce the source and background of this paper,the present research condition at home and abroad,the research content and the pending problem,and establish the research direction and the whole idea.2.Analysis of the factors affecting the channel traffic capacity: By analyzing the meteorological condition, the hydrology condition , the channel’ condition and the type and scale of the crossing ships, providing datas for the establishment of the mathematical model of ship navigation drift and the calculation of the ship track width.3.EstabIishmeng of the mathematical model of the channel’s traffic capacity: According to the channel’s actual characterics , establishing the mathematical model of ship navigation drift in curving and straight channels ,and calculating effective width in differrent depth and the restrictions of the depth of the channel to the traffic capacity.4.Studies of ship’s simulation: According to the simulation studies of various typical ships passing the channel,obtaining the ship’s standards of restricted naviganion in different external conditions trials,confirming that the research results have practive application value by conducting contrastive analysis research with the the theoretical calculation results.5.Conclusion: We conclude the greatest length, the great width, the draft and the corresponding safety measures of the typical sea boats crossing the channel by theoretical calculations and the results of simulation research and comprehensive analysis of ships under the function of various factors.更多还原
