Abstract
Recently, as the velocity of train has been improved and the operation of the express train has been increased, the ground-transmitted vibrations can be a serious problem. For example, the location of a precision machine shop near a railway, or of delicate laboratory apparatus in a plant area containing heavy drop forging machinery or unbalanced rotating machinery are typical situations in which ground-transmitted vibrations may pose serious problems. This paper investigated the reduction effects on ground vibration before and after installing the continuous welded rail on the basis of field tests.
