摘 要: | 刚架拱桥结构兼有拱争梁的特点,斜腿与跨中形成拱的作用承受较大的轴向压力,但只分担较小的弯矩。最近十几年,刚架拱桥的应用在跨径增大、外形变化、应用于连拱、在软地基上修建及施工方法改进等方面不断有所发展,获得良好的经济效益。

Abstract: | Arch bridge structure is featured with arch and beam. The arch formed by bevel-leg and middle span can bear huge axial pressure but small bending moment. In the past decade, the applications of arch bridge in enlarged span, changed appearance, multi-arch and squashy foundation and the construction process of arch bridge has been improved and achieved good economic return. |
