我国城市轨道交通的降噪措施解析

Analysis of noise reduction measures for urban rail transit in China

城市轨道交通行业的发展对城市经济保值增值目标的实现起到了促进作用,但是也使噪音污染等问题衍生出来,这一问题若长期滞留将会对城市轨道交通事业发展起到限制作用。本文对城市轨道交通噪声源与形成机理进行解析的基础上,对城市轨道交通减振降噪几种常见措施的应用效果进行解析。实践证明各类线路以及钢轨设施的应用,在降噪方面发挥的作用是极为显著的,希望在国内城市轨道交通建设环节提供技术指导。

to achieve the goals of the development of city rail transportation industry of city economic value has played a catalytic role, but also make the noise pollution problems derived, if this problem will be long-term retention to restrict the city track transportation development. On the basis of analyzing the noise source and formation mechanism of urban rail transit, this paper analyzes the application effect of several common measures of urban rail transit vibration reduction and noise reduction. Practice has proved that the application of various lines and rail facilities plays a very significant role in noise reduction, and hopes to provide technical guidance in the construction of domestic urban rail transit.
