分析了城市轨道交通的主要噪声源,对其主要减振降噪工程措施进行了综述,并就采用减振型轨下基础的各种措施的减振降噪效果、维修工作量及其难度、造价高低、施工技术难易程度等进行了分析与比较,以期能为我国城市轨道交通建设提供技术参考。
The main noise sources of urban rail transit are analyzed and the main engineering measures of vibration and noise reduction are summarized. And the measures of reducing vibration and noise, the maintenance workload and the difficulty of adopting various measures based on the vibration reduction track, The level of cost, the degree of difficulty of construction technology and so on were analyzed and compared in order to provide technical reference for the construction of urban rail transit in our country.
