【Abstract】 Level rotation of ten thousand tons cable-stayed bridge refers to stability of the bridge in rotation,and requests highly to alignment and internal force of the bridge.Therefore,construction monitoring should be done to entire construction stage and rotational construction stage.Monitoring content,monitoring methods and monitoring precautions in this two stages are introduced from the perspective of bridge basic parameters,bridge alignment,bridge internal force and temperature in and out of the bridge.The results of construction monitoring for Suifenhe cable-stayed bridge are introduced.It is a prestressed concrete cable stayed bridge with one pylon and single cable plane,the rotational weight is 14000t,the rotational angel is 70.4°,the length of cantilever girder is 98m.The results indicate that rotational construction of the bridge is successful and construction monitoring for level rotation of bridge is effective.The monitoring technology can be applied to similar bridges in the future.更多还原
