摘要:

舟岱跨海大桥主通航孔桥是目前世界上最大跨径的三塔钢箱梁海上斜拉桥。根据在舟岱跨海大桥主塔施工安全管理工作的实践经验，分析海上高塔液压爬模施工中的主要安全风险。分别从爬模安装、爬模爬升、爬模日常管理等方面进行介绍，重点阐述海上液压爬模施工安全管理要点和风险防控措施。有关经验可供类似项目专业人员参考。

Abstract:

The main navigable span bridge of Zhoudai Cross-sea Bridge is the largest-span three-pylon steel box beam offshore cable-stayed bridge on the world now. Based on the practical experience in the construction safety management of the main pylon of Zhoudai Cross-sea Bridge, the main safety risks of the hydraulic creeping formwork in the construction of offshore high pylon are analyzed, and introduced from the creeping formwork installation, creeping formwork climbing and creeping formwork day-to-day management. The safety management essentials and risk control measures in the offshore hydraulic creeping formwork construction are specially expounded. The relative experience can be referred for the professionals of the similar projects.
