贵州底那河大桥是一座跨径120m的上承式拱桥,采用常备式钢桁拱架法现浇施工,该拱架是贵州省跨度最大的悬拼拱架。以底那河大桥为工程背景,介绍了常备式钢桁拱架在现浇拱桥施工中的应用,通过拱架施工过程中承载力的计算和整体稳定性计算,对施工方案进行了验算和优化研究,对于此类桥梁施工方案的设计和计算具有一定的借鉴意义和工程实用价值。
Dina River Bridge in Guizhou Province is a over-span arch bridge with a span of 120m. It is constructed by the standing-type steel truss arch method and is the most widely suspended hanging arch frame in Guizhou Province. Taking the Dinahe Bridge as the engineering background, the application of the standing steel truss arch frame in the construction of cast-in-situ arch bridge is introduced. Through the calculation of the bearing capacity and the overall stability calculation in the process of arch construction, the construction scheme is checked and optimized Research, for the design and calculation of such bridge construction program has some reference significance and engineering practical value.
