摘要
东海大桥全长约31 km,工期紧,施工环境恶劣,非通航孔70 m跨下部结构是控制工期的关键工程,通过采用钢管桩、预制混凝土吊箱承台、预制墩身等快捷施工技术,大大加快了施工进度,简要介绍一些设计细节。
The Donghai Bridge totals about 31 km in length. The construction time schedule for the Bridge was tight, construction environment was hash and the construction of substructure of the 70-m non-navigable spans was the critical works that would control the construction time schedule. In the construction of the substructure, the speedy construction techniques, such as those of the steel pipe piles, precast concrete boxed pile caps and precast pier shafts, were used and the construction progress was therefore greatly accelerated. In this paper, some of the design details of the substructure are briefly described.
