저심도 철도 시스템에서의 열차 및 차량의 이동하중에 의한 동적거동에 관한 연구

As a low depth light rail system is getting issued recently, It is important to understand dynamic effects from train and car moving loads. In this study, Numerical analyses were performed to evaluate ground surface vibrations from train and car operations on low depth track system using LUSAS which is finite-element analysis program. The dynamic serviceability of a building is evaluated using analysis results. The evaluated vibratory acceleration under the moving loads of car and train at the depth of 1.0 m is 0.0042 g, 3.0 m is 0.0037 g and the value of 0.00048 g at the depth of 5.0 m. The research results show that low depth train system can be used with low vibration effect by comparing with the maximum allowable criteria of 0.102 g.
