摘要: 基于目前国内外大跨径连续刚构桥出现主跨跨中挠度过大的窘态和危害,介绍了设计、施工、设计与施工等3 类偏差,从3类偏差的角度讨论了连续刚构桥主跨跨中挠度过大的原因,并提出相应的对策,可以为连续刚构桥的 设计和施工提供参考。

关键词: 连续刚构桥, 跨中挠度过大, 设计偏差, 施工偏差, 设计与施工偏差

Abstract: Based on the domestic and foreign long-span continuous rigid frame bridge with the emergence of embarrassment and harm of the large deflection of mid-span currently,three kinds of deviation were introduced,such as design deviation, construction deviation,as well as deviation between design and construction. Then from the point of three kinds of deviation, the causes for large deflection of continuous rigid frame bridge’s mid-span were discussed,and the corresponding countermeasures were also put forward,which can provide some references for the design and construction of continuous rigid frame bridge.

Key words: continuous rigid frame bridge, mid-span’s large deflection, design deviation, construction deviation, deviation between design and construction
