组合式拱桥病害分析及加固
|
摘要
通过对某组合式拱桥结构进行全面检测,分析了桥梁病害产生的原因,提出了在不阻断交通的情况下,利用旧桥本身固有的结构特性对该桥进行合理的改造和加固设计的方法。经过改造与加固后,能显著提高桥梁的承载能力,满足目前的车辆荷载,对类似旧桥的改造和加固设计具有一定的参考价值。
By the comprehensive inspection on the appeared diseases of a modular structure bridge and the analysis of the causes of the bridge disease,a reasonable transformation and reinforcement design method was proposed which uses the inherent characteristics of the bridge structures,without blocking the traffic situation.After transformation and reinforcement,it can significantly improve the carrying capacity of the bridge,and meet the current vehicle load.Meanwhile,it also has a certain reference value on the similar old bridges which need transformation and reinforced design.
