| 摘 要： | 空腹式无铰拱桥因其拱上建筑的联合作用,其受力情况变得较为复杂。以一跨径为30 m的拱桥为例,通过对梁格法模型、单梁法模型及裸拱模型分析拱桥的内力分布特性,在分析比较的基础上,为设计提供方便快捷的计算方法。

| Abstract: | The stress condition of Vierendeel no hinges arch bridge will become more complicated because of combined effect of spandrel structure.Taking one arch bridge with span of 30 m for example,the internal force distribution characteristics of arch bridge are analyzed by means of grid frame method,single girder method and naked arch method models,the convenient calculation method is provided for designers on the basis of analysis comparison. |
