【摘要】：三峡175m蓄水后,库区河段通航环境和通航条件与以往相比发生了较大的变化。一方面,三峡航运呈现良好的增长态势,过坝货运量及过坝各类运输船舶数量均大幅提高；另一方面,三峡库区河段大风大雾阴霾等恶劣天气频繁发生,同时,当三峡坝区出现船闸超过设计流量、船闸计划性停航检修、重大节日开展反恐安保工作等情况时,三峡坝区也会出现大量船舶积压滞留现象。目前,对三峡大坝至庙河河段内按实际情况进行分析测算出锚地的实际需求容量及锚地规划等内容尚未做全面系统的研究。因此,进行三峡大坝至庙河河段待闸锚地建设规划研究是很有必要的,为研究河段的锚地建设工程提供基础资料和重要的技术参考,为坝上锚地分期建设奠定基础。本文首先对三峡大坝至庙河河段内的已建锚地的布置现状、容量大小、锚泊方式等进行了调查,并分析了目前本河段内的锚地运用存在的主要问题是现有锚地可容纳船舶的数量已严重不能满足当前的需求,所以对研究河段进行锚地建设规划已刻不容缓。其次,根据目前本河段内待闸船舶的船型尺度、锚泊方式等分析计算出锚位水深、锚位面积等船舶所需的锚泊参数,并首次利用基于经验公式的静态方法和基于排队论的动态方法分别对三峡坝上待闸锚地所需的锚位数进行了计算分析,同时对这两种方法进行了适用性分析讨论。最后,根据研究河段内合适的可利用的岸线(或水域),分别提出了锚地近期与远期的总体建设规划方案；并建议近期锚地工程合理的建设时机为2015年前建设完工,拟建锚地投入使用,远期锚地工程合理的建设时机为2020年前建设完工,拟建锚地投入使用。
[Abstract]:After the storage of 175m in the three Gorges, the navigable environment and navigation conditions in the reservoir area have changed greatly compared with the previous ones.On the one hand, the three Gorges shipping has shown a good growth trend, with the volume of cargo passing through the dam and the number of all kinds of ships passing the dam increasing substantially; on the other hand, bad weather such as strong winds, fog, haze and other bad weather frequently occur in the river reach of the three Gorges Reservoir area, at the same time,When the ship lock exceeds the designed flow in the three Gorges dam area, the ship lock is stopped and overhauled, and the anti-terrorist security work is carried out during the major festival, there will be a large number of ship backlog and detention phenomenon in the three Gorges dam area.At present, the actual demand capacity of the Anchorage and the planning of the Anchorage have not been comprehensively and systematically studied according to the actual situation in the reach of the three Gorges Dam to the Miaohe River.Therefore, it is necessary to study the construction planning of the Anchorage in the reach of the three Gorges Dam to the Miaohe River. It is necessary to provide basic data and important technical reference for the study of the Anchorage construction of the reach, and to lay the foundation for the phased construction of the Anchorage on the dam.In this paper, the layout, capacity and mooring mode of the built Anchorage in the reach between the three Gorges Dam and the Miaohe River are investigated.The main problem in the application of Anchorage in this reach is that the number of existing Anchorage can not meet the current demand, so it is urgent to study the Anchorage construction planning.Secondly, according to the ship type scale and mooring mode of the ship waiting to be locked in the river reach, the anchoring parameters needed by the ship such as the water depth and the area of the anchor position are calculated.The static method based on empirical formula and the dynamic method based on queuing theory are used for the first time to calculate and analyze the number of anchors needed for the Anchorage on the three Gorges Dam, and the applicability of the two methods is discussed.Finally, according to the study of the suitable available shoreline (or water area) in the river reach, the short-term and long-term overall construction plans of the Anchorage are put forward, and it is suggested that the reasonable time for the construction of the Anchorage Project in the near future should be completed by 2015.The proposed Anchorage is to be put into use. The reasonable construction time of the long-term Anchorage project is the completion of the construction before 2020, and the proposed Anchorage will be put into use.
