摘要:

以某钢管混凝土拱桥为研究对象,开展常规外观检查和桥位水质调查,分别应用《城市桥梁养护技术规范》(CJJ 99—2003)和《公路桥涵养护规范》(JTG H11—2004)对桥梁的状况进行评估。结果表明:该桥评定状况分别属于D级和三类桥,需要进行中修; 2个规范中缺乏与钢管混凝土拱桥有关的专门条款,存在着不足之处; 虽然2个规范对该桥的评定结果相近,但是在上部结构、下部结构和桥面系的状况指数、权重方面存在着一定的差异,其一致性方面的检验还有待更多桥例的验证。

Abstract:

A detection for a concrete-filled steel tubular(CFST)arch bridge was carried out, including general appearance inspection and in-situ water quality investigation. Two criteria, Technical Code of Maintenance for City Bridge(CJJ 99—2003)and Code for Maintenance of Highway Bridges and Culverts(JTG H11—2004)were applied to appraise the technique condition of the bridge. The results show that the bridge is in grade D and the third level respectively, which means that the bridge needs a general repair. The two aforesaid codes have limitation in this process because there are no special items for CFST arch bridges in them. Although the assessment results by the two codes are similar, the condition index and the weight of superstructure, substructure and deck system by these two codes are different. The consistency of these two codes should be checked by more assessment of other bridges.
