第六次铁路提速对沿线环境噪声的影响研究

Influence Study of the Sixth Raising Railway Speed on Environment Noise along the Line

研究目的:针对第六次铁路大提速前后铁路沿线环境噪声变化情况进行研究,以减少人们对沿线环境噪声污染程度增加的担忧。研究方法:对影响沿线铁路环境噪声的4个主要因素,即机车类型、列车运行速度、列车通过频率和轨道状态,进行理论分析,并对第六次铁路提速前后毗邻沪宁线和沪杭线的上海某住宅小区环境噪声进行实地监测,然后将理论和实地监测结果进行相互验证。研究结果:提速前后铁路沿线环境噪声变化不大。研究结论:实施铁路提速后,列车运行速度有了明显提高,而且又没有对环境造成不良影响,取得了较好的经济和社会效益。

Research purposes： Aiming at the variety of environmental noise along the line before and after implementation of the sixth raising railway speed, this paper does the reseach to reduce people＇s worry about the increasing of environmental noise pollution along the line. Research methods：Four principal factors, namely, locomotive style, speed of the train, frequency of the train passing by and track condition, are discussed in the paper, which will influence the environmental noise along the railway after performing raising railway speed. Environmental noise in a residential community nearby Hu - Ning and Hu - Hang railways in Shanghai has been monitored in situ before and after implementation of the sixth raising railway speed. By comparing them with each other, we can verify our conclusion. Research results：There is little difference in environmental noise before and after raising railway speed. Research conclusions：Raising railway speed does not exert a tremendous influence on environment, but has quit good economic benefits and social effect.
