Research on the Application of Full-hall Support Construction Technology in the Cast-in-place Box Girder Project
In order to verify the applicability of full-hall support construction technology in cast-in-place box girder project,this paper analyzes the key points of full-hall support construction technology combined with a bridge project from the aspects of support design,support erection and support preloading and loading.The final preloading monitoring results show that the cumulative settlement value of the lower part of the full-hall support system is less than 4 mm,and the cumulative settlement of the upper part is less than 8 mm,which meets the construction design requirements,proving that the full-hall support construction technology has good application value in the cast-in-place box girder project.
