摘　　要：针对连续梁跨中下挠和腹板裂缝这些影响桥梁后期使用、耐久性及安全性的重要因素,本文分析了连续梁跨中下挠及腹板裂缝的影响因素,在此基础上提出了黄河特大桥连续梁跨中下挠及腹板防裂措施,为特大桥梁工程建设提供了参考。In response to the important factors affecting the later use,durability,and safety of bridges,such as mid-span deflection and web cracks of continuous beams,this paper analyzes the influencing factors of mid-span deflection and web cracks of continuous beams.Based on this,measures for preventing mid-span deflection and web cracks of continuous beams of the Yellow River Super-large Bridge are proposed,providing reference for the construction of super-large bridge projects.
