石拱桥提载加固受力性能分析

Analysis on load-bearing performance of reinforced stone arch bridge

以云南某石拱桥加固为例,采用有限元软件对其进行加固后的受力性能和承载能力分析,同时进行荷载试验对其加固效果进行验证,分析结果表明,该桥加固后的强度及刚度都得到了大幅度的提升,该类加固方法可为今后石拱桥加固提供思路。

This article uses a stone arch bridge in Yunnan as an example,this paper uses finite element software to analyze its mechanical performance and bearing capacity after reinforcement,and at the same time,carries out load tests to verify its reinforcement effect.The analysis results show that the strength and stiffness of the bridge after reinforcement have been greatly improved.This kind of reinforcement method can provide ideas for the reinforcement of stone arch bridges in the future.
