摘　　要：通过对城市桥梁噪声产生的原因及特性进行分析,提出在桥梁建设阶段,在桥面铺装、伸缩缝、声屏障、桥梁结构优化等方面可采取的降噪措施,从而对城市桥梁噪声的噪声源和传声途径进行控制,以保证人民群众正常生活的声环境质量。According to the analysis of the causes and the characteristics of the urban bridge noise,noise reduction methods as low noise road surface,low noise expansion joints,sound barriers and optimum design of the bridge structure could be considered during the bridge construction. So as to control urban bridge noise source and noise transmission method,and to guarantee people’s normal living sound environmental quality.
