宁波-舟山港马岙港区灌门狭口段航道设计

Design of Guanmen throat section channel at Ma’ao harbor of Ningbo-Zhoushan port

宁波-舟山港马岙港区位于舟山中部海域,其中灌门狭口段为该港区进港航道的主要限制段。该狭口段受两侧暗礁和架空线限制,航道水流流态复杂且航道转弯角度大,是舟山地区通航条件最为复杂的海域之一。通过参考国外规范和舟山地区通航经验,结合数模、船舶模拟、实船试验等方法优化炸礁平面布局,结合实测潮流资料优化船舶狭口段通航时机,合理利用电缆悬链线形式提高航道通航能力,给出了复杂岛礁水域的航道设计方法,可为类似工程提供参考。

Ma＇ao harbor of Ningbo-Zhoushan port locates in the central waters of Zhoushan, and Guanmen throat section channel is the main restrictive channel of Ma＇ao harbor. Due to the limit of both sides＇ reefs and the overhead line, the channel has complicated flow and a sharp turning angle, and thus is one of the most complex channel in Zhoushan area. By reference to foreign norms and the experience of Zhoushan-area＇s navigation, the layout of the reef explosion is optimized by mathematical modeling, ship simulation and real ship testing, and the navigation time of ships passing through the throat section of Guanmen is optimized by the measured current data, and the navigational ability is improved by rational using of the overhead line＇s catenary form. This paper gives a design method of channel in complex island waters, and can provide reference for similar projects.
