Abstract

The present study aims to explore the effectiveness of open trench (OT) as a vibration barrier in reducing the ground-borne vibration induced by the moving trains. A numerical investigation has been performed using 2D finite element analysis coupled with infinite elements. The moving train is simulated as a sequence of pulse loads vibrating at different excitation frequencies. The performance of OT in screening the train-induced vibration is evaluated with respect to amplitude reduction ratio (ARR) defined later. The effect of train speed and optimum geometric parameters of OT on the screening effectiveness has been explored in detail.
