The Construction Control On Continuous Rigid Bridge Of Wujiang River

A self-erection system---Cantilevering construction method is used in prestressed concrete continuous rigid bridges. This method brings more complex variety of internal forces and displacements of bridge structure, so the construction control is necessary to ensure the safety and quality during bridge construction. For bridge of WuJiang River, construction control and error adjusting method are studied in this paper.The development history of prestressed concrete continuous rigid bridges was reviewed, and a detail depiction for the design theory and construction method was given, with the international study trend and progression introduced。Then the importance of the study was set forth as follows:1,Analysis the influence caused by each factors to structure internal force and bridge geological shape, accumulate experiences for same bridge.2,Study the construction control method in large span bridges, to improve the construction control technology of this type bridges.
