摘要 郑州黄河公铁两用桥大体积混凝土桥墩按承台、墩座、墩身、墩帽的顺序进行浇筑,采用MIDAS构计算软件分析了桥墩浇筑过程中的温度应力和变形情况,探讨了管冷技术对温度应力的影响,为桥墩防裂提供了应力与变形方面的重要依据。 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.
