港珠澳大桥珠海口岸交通中心结构设计

Structural design of transportation center at Zhuhai Port of Hong Kong-Zhuhai-Macao Bridge

本文介绍了港珠澳大桥珠海口岸交通中心的基础及上部结构设计。由于项目靠近大海及位于人工岛上,针对负摩阻力、不均匀沉降、海水腐蚀、地下室超长等提出了相应的解决措施。地上结构采用预应力混凝土框架结构、屋盖采用双层空间网架+单层网格的大跨度空间钢结构,对主体结构的抗风性能、抗震性能及温度应力进行了分析。分析表明,结构受力性能满足规范要求,可供类似项目参考。

Foundation and upper structure design are introduced of Transportation Center at Zhuhai Port of Hong KongZhuhai-Macao Bridge in this project. Due to this project near the sea and on the artificial island, resolution measures are suggested to negative friction, differential settlement, seawater corrosion, over-length basement. Prestressed Concrete frame structure is used to the upper structure. Long-span space steel structure of double layer grid & single layer grid is used to the roof. Wind-resistant performance, seismic capacity, temperature stress are analyzed on the main structure. The results show that structural performances meet the code requirement, it can be reference for similar projects.
