东海大桥预制墩柱海上架设施工

Construction of Sea Erection of Precast Pier Columns of Donghai Bridge

东海大桥是我国在建的第一座真正意义上的高速公路跨海大桥,建设条件特殊,施工工艺复杂且施工难度高。现详细地阐述通过实践考验的外海桥梁施工新工艺——墩柱整体陆上预制海上架设施工的主要施工工艺和控制方法,希望对类似桥梁的施工起一点借鉴的作用。

Donghai Bridge is the first building express highway bridge over sea in real signification in China. It has special construction condition, construction process and difficult degree for construction. The paper states in details the main construction process and control method of a new construction process of outer sea bridge through the practical examination, i.e. land integral precast of pier columns and sea erection and construction. It hopes to play some roles for reference of the construction of the similar bridges.
