在役石拱桥结构分析理论的探讨

On exploration for analysis theory for in-service stone arch bridge structure

阐述了石拱桥的特点及发展需求,归纳了石拱桥结构分析理论的研究现状,介绍了拱上建筑与主拱圈的联合作用,通过研究拱趾的内力计算模型,得出拱桥的不同工况结构体系也发生变化,要针对不同的情况进行结构分析。

The paper illustrates the characteristics of the stone arch bridge and its development needs,sums up the research situation for the analysis theory of the stone arch bridge structure,introduces the combined role of the buildings on arch and main arch ring,and concludes different construction situations can lead to various structural systems by researching the internal stress calculation model of arch toe,so the structural analysis can be done according to different situations.
