本文对特大桥高墩大跨径连续刚构桥的国内外研究状况进行了阐述,分析了特大桥高墩失稳机理,并且从施工模式、测量技术、墩身混凝土浇筑等多角度、多方面对特大桥高墩稳定性及施工技术方法和关键工序控制进行了探讨。
In this paper, the research status of large-span continuous rigid frame bridge with high pier and super-large span in the world is described. The instability mechanism of high pier in the bridge is analyzed. From the aspects of construction mode, measurement technology, pier concrete pouring, The stability of the high pier of the super large bridge, the construction technology and the key process control are discussed.
