舟山小干大桥通航研究

舟山市普陀区小干大桥连接舟山本岛与小干岛,跨越沈家门西港区。沈家门港是我国著名的渔港,为渔船避风、补给、水产集散,客货运输的综合性港口。沈家门西港区航道由小干岛、马峙岛与舟山本岛所围成,两岸码头众多,航行船舶的组成较为复杂。在分析舟山小干大桥所在的沈家门西港区海道条件、航道条件、港口情况的基础上,从通航的角度,对拟建的舟山小干大桥选址进行分析、对通航净宽进行计算,并结合桥区航道条件,论证通航净空尺度。

On navigation of Xiaogan bridge in Zhoushan

Zhoushan Putuo District Xiaogan bridge links the Zhoushan island with the Little Gan island,and spans the Shenjiamen west harbor area.Shenjiamen fishing port is famous in our country.It is a comprehensive port for fishing boats’ sheltering,re-supply,aquatic products distribution,and passenger transportation.Shenjiamen west harbor channel is surrounded by Xiaogan island,Mashi island and Zhoushan island.There are many terminals on both coasts,and the ships’ composition is more complicated.Based on the analysis of the hydrographic conditions,the navigation condition and port situation of Shenjiamen west harbor area in Xiaogan bridge area,we analyze the site location of Zhoushan Xiaogan bridge to be constructed,and calculate the navigation span from the view of navigation.We also demonstrate on the navigable clearance based on the channel condition in the bridge area.
