| Abstract: | To solve the problem of the actual measured elongation of cast-in-place box girder short beam press-stress steel strands above ± 6% of the current highway bridge standard during construction, detailed analysis and calculation are carried out on the causes of the error combined with the actual engineering projects, and the reasonable suggestions are proposed to reinforce control. |
