Continuous Rigid Frame Bridge Construction Control Method Research And Application

Over the past 20 years, the type of Prestressing Concrete Continuous Rigid Frame Bridge is being widely used in 100-330 m span scope. During the cantilever construction of Prestressed Concrete Continuous Rigid Frame Bridge, the beam axis shape of formed blocks can't be regulated during the next constructions. For the construction of the bridge is finished succssfully, for the beam axis shape is exactitude for design, for internal force of the beam is appeased by design request, the construction control must be done in the construction process of the bridge.The purpose of this paper is to make the line and internal force of Dagangshan Traffic Bridge in the range permitted by the design. It uses the construction control theory of Continuous Rigid Frame Bridge, uses Advancing Analysis, Regression Analysis, Grey Theory Forecast Analysis etc. into the construction control of Prestressing Concrete Continuous Rigid Frame Bridge, and it is controlled, calculated and analyzed by tight theories, and passes the construction monitoring system. Above all, it makes the line and internal force of Dagangshan Traffic Bridge in the range permitted by the design, and got the purpose. We had a successful attempt in the study of Prestressing Concrete Continuous Rigid Frame Bridge's construction control skills.
