摘　　要：我国高速铁路建设受制于征地拆迁及环境保护等影响,经常采用“以桥代路”形式,桥梁工程在线路中占比大,简支箱梁作为桥梁结构中的主要结构形式,越来越多应用于高铁建设中。本文对简支箱梁常用三种施工方法的施工工艺和适用条件进行了总结,并提出了综合造价确定方法,通过工程实例进行施工方案比选,为后续高速铁路简支箱梁施工组织设计提供思路。The construction of high-speed railways in our country is often hindered by factors such as land acquisition,relocation,and environmental protection.As a result,the"bridge instead of road"approach is frequently employed,with bridge projects comprising a significant portion of the railway infrastructure.Among various bridge structures,the simply supported box girder has gained increasing prominence in high-speed rail construction.This study provides a comprehensive overview of three commonly used construction methods for simply supported box girders,including their construction processes and applicable conditions.Moreover,a holistic cost determination method is proposed,and a comparative analysis of construction plans is conducted using a specific project example.The findings of this study aim to offer valuable insights for the subsequent organizational design of simply supported box girder construction in high-speed railway projects.
