城市轨道交通轨道振动噪声成因及整治措施研究

Research on Causes and Treatment Measures of Track Vibration and Noise in Urban Rail Transit

随着我国基础设施建设水平的不断提高,各大城市的轨道交通运营线路数量不断增加,给人们的出行提供了更便利和多样化的选择。与此同时,城市轨道交通运行引发的轨道振动噪声问题日益显现,严重影响着城市轨道交通沿线周围居民的工作、生活和身心健康,也加剧了轨道结构的病害程度。以我国城市轨道交通线路轨道振动噪声问题为研究对象,根据现场调研总结归纳出轨道振动噪声的产生原因,并提出针对性的整治方案;对轨道减振降噪的整治措施进行了评估分析,探讨了整治方案的合理性,并提出轨道减振降噪的运维建议。

With the incessant improvement of Chinese infrastructure construction level,urban rail transit lines are increased in major cities,and more convenient and diversified choices are provided for people to travel.Meanwhile,the problems of track vibration and noise caused by urban rail transit operation are increasingly appeared,and the mental and physical health of the working and living residents along the urban rail transit are seriously affected.The problems also intensify the disease development of track structure.The research object of this paper is the track vibration and noise in urban rail transit.The causes of track vibration and noise are summarized and inducted based on field investigation,and targeted treatment measures are put forward.The improvement measures of track vibration and noise reduction are evaluated and analyzed,rationality of treatment measures are investigated,and suggestions on operation and maintenance of track vibration and noise reduction are proposed.
