摘要
钢-混凝土组合拱桥是根据拱桥主拱的受力特点而衍生出来的新型结构,它的创新点在于拱脚区段为钢箱内填充混凝土,拱顶区段在钢箱顶板上浇筑混凝土。通过工程实例对钢-混凝土组合拱桥过渡段设计进行探讨,提出过渡段相关的设计方案,可供同类工程参考。
Steel-concrete composite arch bridge is a new structure derived from the main arch of arch bridge according to its force bearing characteristics.Its innovative point is that the arch foot section of steel box is filled with concrete and steel box in the arch section of the roof poured with concrete.In this paper,studies on design of the steel-concrete composite arch bridge transition section is done by examples,and relative design solutions are put forward for the reference of relative researchers.
