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.
