도시철도 지반진동 예측을 위한 FRA 진동평가방법의 개선

In this paper, an empirical method for the prediction of ground borne vibration level in urban railway is presented. The general procedure of vibration assessment follows that of the method developed by Federal Railroad Administration(FRA). However, main factors affecting vibration level are modified considering the conditions of train, track, tunnel etc. in domestic urban railway. Vibration levels in the resident buildings neighboring to Keong-ui line are assessed using the presented method.
