| Abstract: | A super bridge on Jing-Hu Expressway is a prestressed concrete continuous rigid-frame box girder bridge. After years of operation, some transverse cracks appear at the bottom of box girder. By testing the bridge, the causes of transverse cracks are determined, the reinforcement project which mainly rely on external prestress with bond is used to reinforce the bridge, which has prominent social and economic benefit. |
