摘要
三角塘沪昆铁路跨线桥全长660 m,其中第4联主桥为三跨预应力混凝土连续梁桥结构,采用挂篮悬臂浇筑法施工上跨韶山灌渠。运用有限元软件对其连续梁桥进行计算,分析不等跨连续梁结构受力特点,得出几点结论,可用以指导不等跨连续梁桥结构的施工图设计。
The total length of the bridge spanning Sanjiaotang Shanghai-Kunming Railway is 660 m, in which the fourth of the main bridge is a three-span pre-stressed concrete continuous girder bridge, and is constructed by the form traveler cast-in-cantilever method overcrossing the Shaoshan Canal. The finite element software is used to calculate the continuous girder bridge, and the stress characteristics of the unequal span continuous girder structure are analyzed. The conclusions can be used to guide the construction drawing design of unequal span continuous girder bridge.
