平潭海峡公铁两用大桥因在恶劣施工环境条件下修建无经验可循,为目前世界上在建的建造难度最大的海峡大桥,本文通过全面研究分析论证,考虑安全、质量、资源配置、施工工效等多方面因素对大临设施设计位置、施工组织、使用规模、结构设计等进行系统的规划设计,确保了大桥的顺利建设,为以后类似工程施工提供借鉴经验。
As there is no quotable experience for construction under harsh environmental conditions,the Pingtan Strait Road-rail Bridge is the most difficult strait bridge to be built in the world. Based on the comprehensive study and analysis,and considering some factors such as the safety,quality,resource allocation and construction efficiency,the paper made a system planning and design of large temporary facilities’ location,construction organization,scale and structure design,so as to ensure the smooth construction of the bridge. It could provide some referential experiences for the construction of future similar projects.
