【摘要】：弯曲航道是船舶在航行中面对的航道形式之一,而弯曲航道的尺度以及水流条件是限制船舶通航的重要关键点,研究弯曲航道的安全通航就显得很有必要。随着我国经济的发展,航运业迎来了自身的机遇期,新弯曲航道的开辟和旧弯曲航道的改造使得船舶通航安全面临重大的考验,船舶自身的大型化、现代化、专业化也要求更高的通航环境,在弯曲航道尺度和通航能力一定的条件下,尽可能使船舶安全、高效的通过,使得有限的航道资源得到充分的利用。本文从弯曲航道安全通航角度出发,重点探讨弯曲航道水流状况,并在此基础上提出了弯曲航道尺度布置及弯曲航道安全通航对策。文章的主要内容包括:第一章:归纳、总结、分析国内外研究弯曲航道安全通航的现状,在前人的基础上总结出弯曲航道安全通航所需要研究的问题。第二章:研究了弯道水流特性及其对通航的影响。第三章:在结合船舶操纵性的基础上提出了弯道航道尺度确定方法。第四章:从“人-机-环境-监管”四个方面研究并提出弯道安全通航对策。本文研究结果表明,弯道航道宽度布置应考虑弯道环流产生的横向漂移量;船舶通过弯道时,船长应加强船舶管理,驾驶员应谨慎驾驶,VTS应严格监管,对不合理的浮标应科学布置,以提高弯道通航的安全度,减少交通事故发生的概率。
[Abstract]:The curved channel is one of the waterway forms faced by ships in navigation, and the scale of the curved channel and the flow conditions are the important key points to restrict the navigation of ships, so it is necessary to study the safe navigation of the curved waterway. With the development of China's economy, the shipping industry has ushered in its own opportunity period. The opening of the new curved channel and the transformation of the old curved channel make the navigation safety of ships face a major test, and the ships themselves become large and modernized. Specialization also requires a higher navigable environment. Under the condition of curved waterway scale and navigation capacity, ships can pass safely and efficiently as far as possible, so that the limited waterway resources can be fully utilized. In this paper, from the point of view of the safe navigation of the curved channel, the flow state of the curved channel is discussed emphatically, and on the basis of this, the scale arrangement of the curved channel and the safe navigation countermeasure of the curved channel are put forward. The main contents of this paper are as follows: chapter one: summarize, summarize and analyze the current situation of research on the safe navigation of curved channel at home and abroad, and sum up the problems that need to be studied in the safe navigation of curved waterway on the basis of predecessors. Chapter 2: the characteristics of bend flow and its influence on navigation are studied. Chapter three: based on ship maneuverability, a method for determining the channel scale of curved channel is proposed. Chapter four: from the four aspects of "man-machine-environment-supervision" and put forward the bend safety navigation countermeasures. The results show that the lateral drift caused by the curve circulation should be taken into account in the channel width arrangement. When the ship passes the bend, the master should strengthen the management of the ship, the driver should be careful to drive, the VTS should be strictly supervised, and the unreasonable buoy should be arranged scientifically in order to improve the safety degree of the bend navigation and reduce the probability of the traffic accident.
