Abstract

The synchronous top-pushing method of construction offers advantages such as a relatively short construction period, smooth pushing process, and simplified traffic management. In recent years, it has been widely adopted for constructing overpass bridges on operational highways. Currently, there are no explicit regulations regarding the monitoring and measurement parameters for the synchronous top-pushing construction of steel box girders. This paper, based on an engineering case study, investigates the impact of monitoring and measurement parameters on the primary internal force and geometric state parameters during the synchronous top-pushing of steel box girders. By comparing multiple measured values with theoretical values and evaluating their influence on girder pushing control, it is recommended that key monitoring parameters should focus on the lateral deformation coordination (north-south side displacement difference), deformation coordination between the main girder and guide girder, and settlement of support points.
