斜靠式系杆拱桥设计与施工要点

摘要

以实际工程为背景,利用Midas软件建立有限元模型,对斜靠式系杆拱桥进行了静力分析和稳定分析.结果表明:斜靠式系杆拱桥在成桥阶段、运营阶段静力验算满足规范要求,结构整体稳定性满足规范要求.最后,对斜靠式系杆拱桥主要施工工艺作了介绍.%Taking practical engineering as the background, the static analysis and stability analysis on the inclined tied-arch bridge are made by utilizing Midas software to build a finite element model.The results show that: the static checking of inclined tied-arch bridge can meet standard requirements in the stage of bridge completion and operation, and the overall stability of the structure can meet standard requirements.Moreover, the main construction technology of inclined tied-arch bridge is also introduced in this paper.
