Multi-span Continuous Curved Girder Bridge Construction Monitoring And Control

The thesis studies and analyzes construction controlling of continuous bow beam bridge. On the basis of data collection and analysis, the paper draws lessons from the newest research achievement of construction controlling in bridge, and studies controlling of construction in continuous bow beam bridge with brackets.Through analysis stuucrural stress and deformation, the paper putts forwsrd the theory and method of construction controlling.Directed against the characteristic of continuous bow beam bridge,the paper discusses that the sensibility of construction parameters affect construction controlling and giues contents and method of parameter readjustment.On the basis of the analysis of structural computation theory,the thesis gets the computation ways of some parameters, meanwhile,it analyses and compares the resuts of bow beam bridge and Stright beam bridge.Associating the practical engineering project, the paper mcilds the monitoring system of bridge. Though compartion and analysis of the collection data and the computation result.it proofs that is successful to control bridge construction.
