整体式钢浮箱在跨海大桥桥墩施工中的综合运用

Comprehensive Application of Integral Steel Floating Box in Construction of Pier of Crossing-sea Bridge

在水中进行墩基础和防撞设施施工,搭设操作平台是关键,在风大浪急的外海,施工难度更大。该文结合东海大桥主通航孔辅助墩及其防撞墩施工的成功经验,为平台设计和搭设、承台吊箱围堰设计和防撞墩施工等提供了一揽子解决方案,可供类似工程参考和借鉴。

It is a key to erect the operation platform for the construction of the pier foundation and the anti-collision facilities in the water. It is ever more difficult to construct on the external sea where the wind is strong and the waves are high. Combined with the successful experience in the construction of the auxiliary pier and the anti-collision of the main navigational span of Donghai Bridge, the article provides a list of solving schemes for the design and the erection of the platform, the design of the cofferdam of base slab overhang box and the construction of the anti-collision pier, which can be referred for the similar projects.
