三跨连续弯石拱桥的设计与思考

摘要

In this paper,three span continuous curved stone arch bridge as an example,intro-duces the stress characteristic and the design thinking of this kind of bridge,the bridge space calculation software MIDAS CIVIL to the whole bridge structure static analysis,and put forward the construction scheme of the early drop frame.%以三跨连续弯石拱桥为例，介绍了该类桥梁的受力特点及设计思路，采用桥梁空间计算软件 MIDAS CIVIL对全桥进行结构静力分析，并提出早期落架的施工方案。
