摘要
结合某大跨径钢筋混凝土箱形的加固实践,提出了拱圈空腹段拱背增大截面,实腹段拱底粘贴钢板带的综合加固处治措施,并通过加固前后结构承载能力的对比分析,验证了加固方法的合理性,为类似桥梁维修处治提供参考。
Combining with the large-span steel reinforced concrete box-style reinforcement practice,the paper puts forward comprehensive reinforcement measures by combining enlarging arch section of hollow arch ring and bottom arch bonding steel plate. Through comparatively analyzing structural bearing capacities before and after reinforcement,it testifies the rationality of the reinforced method,which has provided some guidance for similar bridge maintenance and processing.
