摘要: 通过对某砼空心板简支梁桥病害的调查,分析了该类桥梁病害的产生机理,提出了一种新的加固方法——体 外横向预应力加固技术.通过该桥加固前、后的动静载试验,评析了该桥的加固效果.证明采用体外横向预应力技 术加固空心板简支梁桥效果明显
关键词: 横向体外预应力, 加固, 空心板, 简支梁桥, 动、静载试验
Abstract: The defects of a concrete voided slab bridge are described in this paper. The reasons that cause the deterioration are interpreted. A new approach (Transverse External Pre-stressing) is introduced. The effectiveness of the strengthening is validated by field comparison tests
Key words: transverse, xternal Pre-stressing, strengthening, voided slab bridge, loading test
