防治高速铁路噪声、振动和电磁场污染

PREVENTION OFNOISE,VIBRATION AND ELECTROMAG-NETIR FIELD POLLUTIONS OF HIGH-SPEED RAILWAYS

随着车速的提高，列车的噪声和电磁波污染越来越严重。本文在分析了噪声源特性的基础上，对隔声墙的降噪特性给出了数学分析，其结果对于隔声墙的各种设计参数的选择有指导意义。同时，本文还对高速列车的电磁场干扰特性给出了数学分析，以利于进一步实验和研究。

With the increase of train velocity,the train'snoise and electromagnetic wave pollutions are becoming more and more serious. Based on the analysis of the specific propertiesof noise source,this paper makes a mathematical andysis of the sound reduction character-istves of noise-obstructing-wall.Its results are instructive to the selection of the design parameters of the noise-obstructing-wall.Meanwhile the electromagnetic field interferenceproperty of high-speed trains is also analyzed with mathematical method,for the benefit of further experinent and research.
