Compared with the newly-built expressway project,the design of the widened bridge in the reconstruction and expansion project is relatively complex,with many limiting factors and large calculation difficulty.Based on the Shenshan reconstruction and expansion project of the Beijing-Harbin expressway,the relevant technical issues in the widening design scheme of Qilitai bridge are analyzed,and the key points of widening design,the design ideas of gantry pier steel cover beam,and the key points of widening construction technology are summarized,so as to provide reference for the widening design of bridges in similar reconstruction and expansion projects.
