摘要
针对已建成的跨径组合为112+208+112 m的三桁式刚性悬杆加劲连续钢桁梁桥的工程特点,利用ANSYS有限元软件,对顶推法施工方案进行了施工过程受力分析和进一步探讨,为类似桥梁的施工方案的选择提供了借鉴、参考。
According to engineering characteristics of the completed three trussed rigid suspension bar stiffened continuous steel truss bridge with a span combination of 112 ＋ 208 ＋ 112 m, with the ANSYS finite element software, the construction process stress is analyzed and discussed for the method of jacking construction scheme, which may provides reference for the choice of construction scheme of similar bridge.
