Based on the pushing installation project of the Xiduohe Bridge steel box girder,the key points of continu-ous steel box girder construction technology were elaborated.Due to the location of the bridge in the mountainous area,in order to overcome the unfavorable factors in the installation of steel box girder,measures were taken through reason-able planning,including construction preparation,pushing installation of steel box girder,girder dropping and on-site painting work,which successfully achieve the pushing installation of steel box girder for bridges in mountainous areas.The results show that the reasonably planned scheme not only efficiently completes the installation of steel box girder,shortens the construction period,but also effectively controls the installation accuracy of steel box girder,ensuring the safety and quality of construction.
