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.
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.
