跨海通道影响下大连湾水域规划调整方案比选

Adjustment plan of Dalian Bay water area under influence of cross-sea traffic project

介绍了受大连湾跨海交通工程影响而开展的大连湾水域规划调整方案比选研究过程。针对大连湾内水域通航环境,分析了港口及相关产业的发展趋势,综合预测了各港区通航代表船型。以大连湾跨海交通工程北桥南隧线位方案为边界条件,根据大连湾水域条件和通航需求,通过引入“具有一定保证率的通航代表船长”的概念,合理确定了跨海通道桥梁与锚地、航道边界的安全距离。给出3种调整方案并进行比选分析,提出了工程后续实施过程中需注意的问题。

The research process of the adjustment plan of the Dalian Bay water area under the influence of a cross-sea traffic project was introduced in this paper.According to the navigation environment in the Dalian Bay water area,the development trend of the port and related industries was analyzed and the representative ship types of navigation in each port area were predicted.Using the design scheme of the north bridge and south tunnel of the Dalian Bay cross-sea traffic project as boundary conditions,according to the conditions and navigation requirements of the bay waters,the safe distances between bridge and anchorage,bridge and channel boundary were reasonably determined by introducing the factor of representative navigation vessel length with certain assurance rate.Three solutions for the adjustment plan were given and compared.Issues that needed to be paid attention to during the subsequent implementation stage were put forward.
