Constructional process of cast-in-site box beam of interchange overpass bridge in Jingzhou is expatiated from setting structural support of bottom moulding board,preloading on system of bottom moulding board,setting outside moulding board,bottom moulding board of wing board and core moulding board to construction of reinforcing steel bar and cast-in-site of concrete.

Geotechnical Engineering Condition of Chepi Flying Bridge Indicated in Guangzhou;

The design for flying bridge landscape is an important content in expressway project.

By way of example of construction protection for the overpass bridge of Xiaonan Grade Separation Interchange crossing Beijing-Zhuhai Expressway,this paper gives a brief account of the construction protection and traffic channeling schemes for the construction of bridges(over) existing expressways.

During the design of the overpass bridge at the urban intersection, it is often simultaneously required to consider the pedestrian cross-street facility.

However, it is of common occurrence that collision occurred between superelevation vehicles and overpass bridges because of bridge clearance limitation or driving in the wrong way.
