摘要:

青兰高速邯郸段跨南水北调总干渠大桥为单承载面下承式钢管混凝土拱桥。文章基于大型通用有限元程序ANSYS,采用组合有限元法建立大桥的有限元模型,对其施工阶段和成桥阶段的整体稳定性进行分析,为大桥施工和运营的安全提供技术保障。

关键词: 钢管混凝土拱桥, 有限元, 稳定性

Abstract:

The bridge cross main trunk canal of the south to North Water Diversion Project in Handan section of the QingLan expressway is a single supported through concrete filled steel tube arch bridge. Based on the large-scale general finite element program ANSYS, the finite element model of the bridge is established by using the combined finite element method. The overall stability of the bridge is analyzed during the construction and completion stages, which provides technical support for the safety of the bridge construction and operation.

Key words: concrete-filled steel tube arch bridge, finite element, stability
