摘要
基于预拱度的设计原理,阐述了钢管混凝土拱桥拱轴线在不同工况作用下的偏离形式,并探讨了影响拱轴线变化的相关因素及预拱度设置的方法,积累了该类拱桥的设计和施工经验。
Based on the design principle of pre-arc, some deviate forms of the arch axis of concrete filled steel tube arch bridge under different load conditions are expatiated, and the impacts of changes in relevant factors arch axis and the pre-arc setting method are discussed, acumulat- ing experiences for the design and construction of such arch bridgse.
