| 摘 要： | 已使用10 a的旧桥预应力混凝土空心板的破坏荷载试验研究,分别基于荷载横向分布和单板受力模式进行相应活荷载效应计算及抗力-荷载效应分析,以确定旧桥预应力混凝土空心板的安全性和可靠性．分析结果表明,“单板受力”状态削弱了桥梁结构的整体作用,降低了桥梁的整体承载能力和上部结构的安全性,给行车安全造成了隐患．该结论为在役预应力混凝土空心板桥的加固改造提供了试验及计算依据．

| Abstract: | Based on destructive the result of destructive load of a 10-year-old pre-stressed concrete hollow slab and on the load distribution and the single-load model, the resistance-load effect analysis and calculation are discussed separately to evaluate the reliability and safety of the used pre-stressed concrete hollow slab. The analysis result indicates that the single slab load mode decreases the reliability and safety of the up-structure, which will bring problems to the further service of the structure. This... |
