Stress Analysis of High Thin-Walled Box Girder Bridge in Chong He Bridge

Abstract:

Based on the Chong He Bridge as research object, this paper expounds the purposes, methods and analysis results of prestressed concrete continuous thin-walled box girder bridge in the process of cantilever construction. The purpose of the research is to make a reasonable structure which meets the designed stress monitoring and to ensure the quality of construction. The method is to layout stress control points in the main control section and conduct real-time control. The result shows that the beam stress is within the safety range and can predict that the structure meets strength requirements in next stage. The conclusion is that through the data analysis, the results guide the whole process of bridge construction as well as fit the design plan.
