| Abstract: | The structure stress of interchange ramp bridge is different from that of straight bridge.The torque of interchange ramp bridge is usually higher than the straight-line box girder bridge,especially when the bridge is under the action of the coupling effect of bending and torsion.This paper mainly introduced computation method and the special structure detail of interchange ramp bridge in Parrot continent connection projects,including diaphragms of box girder,torsion resistance steel,expansion joint and selection and arrangement of the supports. |
