一、前言为适应新干线的高速化和社会经济的发展，必须加强沿线的环境保护。一般来说，由于隧道、桥梁结构物和路基方面的防振措施成本较高，如果对轨道采取有效的防振对策，则不仅费用便宜，且效果较好。本文将介绍有关轨道振动的实况，以及防振轨道的性能试验结果。二、关于 I. Preface In order to adapt to the speeding up of the Shinkansen and the social and economic development, environmental protection along the line must be strengthened. In general, due to the high cost of anti-vibration measures in tunnels, bridge structures and subgrade, effective anti-vibration measures on the track are not only cheaper but also more effective. This article will introduce the live situation of orbital vibration, as well as the vibration test results of the performance of the track. Second, about
