| Abstract: | There were four stages in the mass concrete construction of the substructure of Zhengzhou Yellow River Bridge for railway and highway cast by order of pile Cap, pier platform, pier body, pier cap. In this article, applying Midas software, the temperature stress and the deformation were analyzed during the cast of pier and the influence of the technique of cooling pipe on the temperature stress was discussed,which provided the tress and the deformation against the pier crack. |
