城市快速路改建工程噪声治理中的创新实践

Innovative Practice in Noise Control of Urban Expressway Reconstruction Project

城市快速路改建工程大多采用高架与地面道路相结合的复合道路形式,通常具有车流量大、声源复杂和噪声治理难度大等特点。为提升此类复合道路的噪声治理效果,以上海市济阳路快速路改建工程为例,在对道路沿线敏感点目标受到的噪声影响进行分析的基础上,结合项目的噪声治理目标,提出适宜的噪声综合治理措施,并从声学设计和建筑景观设计2个方面对采用的声屏障进行优化设计,使项目在满足噪声治理需求的同时,起到美化城市景观的效果,为类似工程的降噪实践提供参考。

The reconstruction of Urban Expressway mostly adopts the combined form of elevated road and ground road,which is characterized by large traffic flow,complex sound source and difficulty in noise control.In order to improve the noise control effect of this kind of compound road,taking the reconstruction project of Jiyang Road Expressway in Shanghai as an example,based on the analysis of the noise influence on the noise-sensitive objectives along the road,combined with the noise control goal,this paper puts forward the suitable comprehensive noise control measures,and carries on the optimization design to the adopted noise barrier from the acoustic design and the architectural landscape design,the project can not only meet the need of noise control,but also beautify the urban landscape,and provide the reference for similar projects.
