本文主要研究双肢薄壁高墩连续刚构桥悬臂施工稳定性,对平衡悬臂施工技术的发展概况进行了简单了解,对悬臂施工的两种形式做了简要分析,从设计角度入手,对双肢薄壁高墩连续刚构桥悬臂施工稳定性进行了研究,旨在为提高我国大跨度连续性桥梁的建设水平提供理论参考。 This article mainly studies the stability of the cantilever construction of the continuous rigid frame bridge with double limbs and high piers, and gives a simple understanding of the development of the cantilever construction technology. The two forms of the cantilever construction are briefly analyzed. From the design perspective, The stability of the cantilever construction of the continuous rigid frame bridge with thin-walled high piers is studied in order to provide a theoretical reference for improving the construction level of long-span continuous bridges in our country.
