长江北支航道防台锚地选址方案研究

Site selection scheme for typhoon prevention anchorage in north branch channel of Yangtze River

长江口北支航道北岸规划了启海作业区寅阳码头区,港口建设促进当地海工船舶产业发展,但也面临锚地布局规划欠缺、码头防台能力不足等问题。从沿线企业防台需求、锚地分布、防台措施安全隐患等角度,论证北支防台锚地布局的必要性;从潮流泥沙、河势、水深、规划、工程协调性等方面分析北支下段锚地建设条件,提出防台锚地选址方案。研究表明:北支航道BZ3#至BZ2#红浮南侧水域的水深条件相对较好,距北岸寅阳码头区较近,呈微淤趋势但处于淤积萎缩状态,是布置防台锚地较理想的位置,可为后续港口规划调整提供参考。

In the north bank of the north branch channel of the Yangtze River Estuary,Yinyang port area of Qihai operating district has been planned.The port construction promotes the development of local marine ship industry,but it also faces problems such as the lack of anchorage layout planning and insufficient typhoon prevention capacity.This paper focuses the necessity of typhoon prevention anchorage layout in the northern branch from the aspects of the typhoon prevention requirements,anchorage layout and safety hazards of typhoon prevention measures,and analyzes the construction conditions of the anchorage in downstream of north branch channel from the aspects of tidal sediment,river regime,water depth,planning and engineering coordination.Then a site selection plan for typhoon prevention anchorage is proposed.The research results show that the area on south side of the red float from BZ3#to BZ2#is a suitable location for arranging typhoon protection anchorage,which has relatively advantageous water depth conditions,and it is close to the Yinyang port area,showing a slight siltation trend but in a state of siltation shrinkage.This research can provide reference for port planning adjustments in the future.
