Lateral Displacement Alalysis of Curved Prestressed Continuous Concrete Rigid Frame Bridge

Zhang Liu-chu

Abstract

Except the set of pre-camber,the main piers of curved prestressed continuous concrete rigid frame bridge also has the pre-camber.Based on analyzing the characteristics of spatial deformation of the curved prestressed continuous concrete rigid frame bridge with high piers and long-span,to make an analysis of the effects on the deformation of main pier which are caused by all kinds of the working conditions in the construction stages.Through a real engineering project, build a three-dimensional finite element model to calculate and analyze the lateral displacement of curved prestressed concrete rigid frame bridge in the construction stage.The study may provide scientific evidence for the set of pre-camber of main piers and some suggestions for design,construction and monitor.
