摘 要: 结合文明特大桥-薄壁高墩大跨连续刚构桥的工程实例,采用MIADS软件的壳单元建立该桥12#高墩施工桥阶段的分析模型,分析中考虑双重非线性的影响,研究其在不同工况作用下的稳定性能。同时进行混凝土强度等级、高墩的壁厚和横系梁的设置等参数对高墩稳定性的影响分析,分析结果可为类似工程提供一定的参考。
关 键 词: 桥涵工程;薄壁高墩;续刚构;稳定性;影响参数

Abstract: In this paper, according to the bridge example of the Wen-ming super bridge, which is the thin-walled high pier and long-span continuous rigid frame bridge, the analysis model of 12# high pier building in this bridge was constructed using the shell element of MIADS software. During the process of analysis, the influence of the double nonlinear was considered, and its stability was analysed under different working conditions. At the same time, the effects of some parameters such as concrete strength, the wall thickness of high pier, the setting of straining beam on the stability of bridge were discussed. The results could provide valuable references for similar projects in the future.
Key words: bridge and culvert engineering; thin-walled and high pier; continuous rigid frame; stable behavior; effect parameter
