摘要
结合宜万铁路某预应力混凝土高墩T构桥,选取了合适的主梁和桥墩温度场模式,建立了全桥的空间有限元模型,对主梁产生的温度变形和温度应力进行了分析研究。
Based on one tall-pier T-shape rigid frame prestressed concrete bridge in Yiwan railway, the proper temperature field pattern of girder and pier are selected, the entire bridge spatial finite element model is established, and the temperature deformation and temperature stress of box girder are analysised.
