大跨连续刚构桥施工过程分析

Construction Process Analysis of Large-Span Continuous Rigid Frame Bridge

大跨径连续刚构桥通常采用悬臂浇筑法施工。建立某大跨连续刚构桥的有限元模型,采用正装计算法对其施工过程进行模拟分析,得到了各个施工阶段的应力结果,可为同类桥梁的设计和施工提供参考。

Cantilever pouring method is usually used in the construction of large span continuous rigid frame bridge. The finite element model of a large-span continuous rigid frame bridge is established, and the construc- tion process is simulated by forward-analysis method. The stress results of each construction stage are obtained, which can provide reference for design and construction of similar bridge.
