In particular, large-span prestressed concrete cast-in-place box girders are widely used in railway bridges in mountainous areas with restricted terrain. Most railway bridges using cast-in-place box girders have many tunnels before and after the bridge, and prefabricated box girders cannot be used for erection. In particular, the safety factor of high-pier bridges using the bracket construction method is low, and only the mobile formwork method can be used to make beams.
