Construction Control And Comparative Analysis Of Curve High Pie Continuous Rigid Frame Bridge

The curve continuous rigid frame bridge integrated with the characteristics of the curve bridge and the continuous rigid frame bridge. Therefore, set the lofting elevation and calculation the pre-camber will be more complicated in the contrl of the construction process. In this paper,Using finite element structural analysis software MIDAS-Civil to analysis the characteristics of the deformation(Vertical deformation; horizontal deformation; torsion deformation), the force and the construction control method of the curve continuous rigid frame bridge with the engineering practice. Accordingly neutrality of the construction process-control elevation to provide a scientific basis.The main tasks and results are as follows:1. Introduced the development of the curve continuous rigid frame bridge, and expounded the construction control method of the curve continuous rigid frame bridge.2. Deduce the formula of the pre-camber or the curve continuous rigid frame bridge, and intrudes the method of setting the lifting elevation .analysis of the stress error in the monitor of the construction process, and deduce the practical formula of the monitor stress.3. Targeted at the largest cantilever stage of the curve continuous rigid frame bridge. Analysis of the Structural deformation under the dignity, the blue linked to load, the shrinkage deformation, the second dead load and the live load and support proposal on the torsion pre-camber.4. Examples of the curve with engineering continuous rigid frame bridge (Shilianghe River Bridge) lifting elevation control and error analysis.
