レール凹凸と沿線騒音等に関する経時変化調査

抄録

Rail grinding has been widely carried out both to remove rail deterioration-rail shelling and to reduce rolling noise. In order to investigate the relationship between rail roughness and wayside noise, the measurements of rail roughness and wayside noise have been carried out for 27 months. In this paper, the time-series changes of the rail roughness is first investigated, and, then, the associated wayside noise with the changes is discussed.
