对列车运行产生噪声、振动的对策，由于近来速度提高，更显出其重要性，在整奋新干线建设中，减少建设投资和维修费用，以及同高速化和环境保护相协调的问题都是关键问题。为了适应这种形势，开发了多种防振型轨道，现以板式轨道为中心，就其现状和最近的研究以及今后展望加以叙述。 Countermeasures against noise and vibration caused by train operation have become more and more important due to the recent speed increase. In the construction of the Shinkansen project, the problems of reducing construction investment and maintenance costs, coordinating with the speeding up and environmental protection are all The key issue. In response to this situation, a variety of anti-vibration orbits have been developed, now focusing on plate orbits, describing their current status and recent research as well as their future prospects.
