结合福建平潭海峡大桥施工现场广阔的海域、深水及气候环境等条件,研究了海上深水长大直径桩基、承台的定位与控制技术。在对现有测量技术与控制网特点分析的基础上,提出了更为适应复杂环境条件下桥梁基础施工的定位控制技术与方法。该研究成果解决了复杂环境条件下平潭大桥桩基础的施工定位问题,对相关工程具有重要的借鉴价值。
Combined with the vast sea area, deepwater and climatic environment of the construction site of Pingtan Strait Bridge in Fujian Province, the positioning and control technology of pile foundation and cap of large diameter offshore deepwater are studied. Based on the analysis of the characteristics of the existing measurement technology and control network, the positioning control technology and method that is more suitable for the construction of bridge foundation under complex environment conditions are proposed. The research results have solved the problem of construction positioning of pile foundation of Pingtan Bridge in complex environment and have important reference value for related projects.
