Due to the special geographical conditions near Daguu Island, the Donghai Bridge adopts the prestressed concrete pushing continuous beam structure. The bridge is on a circular curve with a radius of 2500 meters and the total length of the pushing beam is 400 meters. This paper introduces the structural design features of this section. The plane analysis program is used to check the structure safety in the construction stage. The design of construction technology and some special construction measures to meet the requirements of curve pushing in construction are emphatically introduced.
