摘  要:德国2019年开始对境内铁路噪声实施在线自动监测,至今已积累大量数据。基于对铁路噪声测量站设置原则及监测系统组成的概述,重点对德国铁路监测数据进行分析,给出德国目前客货共线铁路网整体噪声水平和各测量站噪声水平,并提出货物列车车流量是影响各站噪声水平的关键因素,为后续研究基于噪声水平的车流量优化问题提供参考。Germany has carried out on-line automatic monitoring of railway noise in 2019.A large amount of data has been accumulated so far.After summarizing the setting principles of railway noise measurement stations and the composition of monitoring system,this paper focuses on the analysis of German railway monitoring data,gives the overall noise level of German passenger freight railway network and the noise level of each measurement station,and preliminarily points out that the running flow of freight cars is the key factor affecting the noise level of each station,so as to provide reference for the follow-up study of train traffic volume optimization based on noise level.
