| Abstract: | Aimed at 9 000 kN girder transporter for high-speed railway bridge construction, the structural in- tensity and flexure stability are calculated with the finite element software. The stress distribution of girder trans- porter is analyzed, and the dangerous parts of flexure stability are found out, which provides reference for structure improvement of girder transporter and monitoring construction. |
