跨海大桥跨海段施工 ,由于受海浪、台风等多种因素的影响 ,施工难度相当大。如何减少海上作业时间 ,确保工程施工安全和工程质量 ,选择切实可行的施工方案就显得尤为重要。东海大桥目前是国内第一座跨海大桥 ,施工环境相当恶劣 ,工序复杂 ,影响因素多 ,工程量大 ,工期紧迫。该桥跨海段承台施工 ,采用预制钢筋混凝土套箱方案 ,有效地缩短了海上作业时间 ,加快了工程进度 ,使工程质量和施工安全得到了保证 Cross-sea bridge across the sea construction, due to the impact of many factors such as sea waves, typhoons, construction is quite difficult. How to reduce the time at sea to ensure construction safety and project quality, select a practical construction program is particularly important. Currently, the Donghai Bridge is the first cross-sea bridge in China. The construction environment is rather harsh, the procedures are complicated, the influencing factors are numerous, the engineering quantity is large and the construction period is urgent. The bridge across the sea cap platform construction, the use of prefabricated reinforced concrete box program, effectively reducing offshore operations, speed up the progress of the project, the project quality and construction safety has been guaranteed
