Analysis of Key Construction Techniques for Prestressed Concrete Beam Bridges
In order to ensure the construction quality of prestressed concrete beam bridges,the form and stress characteristics of continuous beam bridges are summarized,and the construction process and characteristics of cantilever pouring method are analyzed.At the same time,taking a continuous box girder bridge on a certain highway as the research object,the construction points were analyzed from the aspects of 0#block support calculation,temporary consolidation of pier and beam,hanging basket preloading,closure,etc.Finally,the construction control methods of the continuous girder bridge were elaborated from the perspectives of linear control and stress control.The research results can be used as a reference for similar bridge structure construction.
