摘　　要：预应力简支箱梁具有受力明确、构造简单、耐久性好、施工便捷等优点,是高速铁路桥梁的主要结构形式。简支箱梁结合桥隧工程情况、拆迁工程量、场地条件等因素可采用现浇或预制架设的施工方式。此文以新建福州至厦门铁路DK16+385.27~DK42+331.83段线路简支箱梁施工方案为切入点,从工期、运梁通道、梁场选址等方面进行研究,并通过比较分析,以期对类似工程建场方案的确定提供参考。Prestressed simple-supported box beam is the main structural type in high-speed railway bridges owing to its simple mechanical and construction characteristics and good durability.And they can be constructed by method of cast-in-place or fabrication,considering the overall condition of project,the amount of removal,and natural environment.This paper conducts a comparative scheme study through project duration,beam transportation way,and site selection of fabrication field based on the new railway segment DK16+385.27~DK42+331.83 from Fuzhou to Xiamen,aiming to provide a reference for similar engineering projects.
