摘　　要：为了研究中国公路与城市桥梁技术状况评估方法的差异,对《公路桥涵养护规范》(JTGH11—2004)和《城市桥梁养护技术规范》(CJJ 99—2003)进行了比较分析,应用2本规范对1座钢筋混凝土简支梁桥和1座钢管混凝土拱桥进行了检测与技术状况评估,对评估结果进行了对比分析;并对2本规范评估方法一般性内容进行了比较。结果表明:2本规范对桥梁技术状况评估均采用构件加权法,但具体方法、内容均存在一定差异;运用2本规范方法得出的2座桥的桥面系、上部结构和下部结构3个部位的评估结果相近,但上、下部结构的权重差异较大,导致全桥技术状况等级评估结果差异很大;研究结果可为中国道路桥梁技术状况评估方法提供参考。To study the difference of the technical condition rating methods for highway bridges and city bridges in China, a comparison analysis of the rating systems of the Code for Maintenance of Highway Bridges and Culverts （JTG Hll--2004） and the Technical Code of Maintenance for City Bridge （CJJ 99--2003） was carried out. A simple RC beam bridge and a concrete filled steel tubular arch bridge were investigated and their conditions were rated by the two codes, and the rating results were analyzed. In addition, the rating methods in the two codes were compared. The results show that both of them adopt the member weight method but there is difference in detailed approaches and contents; the rating results of the deck systems, the superstructures and the substructures of the two bridges by the two codes agree well, while the rating results of the whole bridges are quite different because the weighing values of superstructures and substructures in the two codes have great difference. This study can provide reference for the condition rating of road bridges in China.
