珠海某跨海通道主桥方案设计

Scheme Design of Main Bridge of a Sea Crossing Channel in Zhuhai

某项目位于珠江口海域,建设条件极为复杂,需克服强台风、高烈度地震、强海水腐蚀、高船撞力等不利的建设条件。项目主桥采用主跨700 m的斜拉桥,通航5万吨级,为崖门出海3个航道中通航吨位最高的航道。就主桥方案设计进行详细论述,可供类似工程项目参考。

The project is located in the Pearl River Estuary,and the construction conditions are extremely complex.It is necessary to overcome the adverse construction conditions such as strong typhoon,high intensity earthquake,strong seawater corrosion,high ship colli‐sion force.The main bridge of the project is a cable-stayed bridge with a main span of 700 m,with navigation capacity of 50000 tons,which is the channel with the highest navigation tonnage among the three channels to the sea.The main bridge scheme design is discussed in detail,which can provide reference for similar projects.
