摘要
根据国内外资料,虽然无碴轨道具有轨道稳定性高、刚度均匀性好、结构耐久性强、维修工作量显著减少等优点,但与有碴轨道相比,存在弹性较差、环境振动和噪声较高的缺点。为解决这一问题,国内外进行了大量研究工作,提出了不同解决方案,主要有:道床隔振、增加线路下部结构的刚度和质量、吸声道床、声屏障等,取得了一定的效果。
According to domestic and external reports, noise ＆ vibration reasearch situation of non-ballasted track on high-speed railway and special passenger railway is reviewed, techniques used to control noise and vibration of high-speed railway track are concluded as well in this paper.
