ANALYSIS AND RESEARCH ON TEMPORARY SUPPORT LAYOUT IN STEEL BOX BEAM TOP PUSH CONSTRUCTION
Taking a bridge project spanning a certain expressway as an example,this study analyzed the influence of temporary support layout on the stress of steel box girders during top pushing construction.Based on numerical simulation methods,a steel box girder top push model suitable for practical engineering was established.The maximum stress and displacement values of the main beam and guide beam under different working conditions were extracted,and their changes were analyzed.The research results are expected to provide reference for similar projects.
