ABSTRACT: In this paper, a study on the characteristics
and the reduction methods of ground vibration due to the tilting train
travelling in the conventional line is carried out. The load transmitted into
the ground is computed considering the interaction between the tilting car and
the line. This load is then applied in the numerical model for the analysis of
ground vibration due to the travelling tilting car. The far-fields of the numerical model are modeled
using the dashpot, as one of the most widely used absorbing boundaries in finite element analysis. Using this
numerical model, the analysis of the ground vibration characteristics caused by
the travelling tilting car and the analysis of the blocking effect of the ground
vibration by wave barriers are performed. From the numerical analysis, it is
shown that the blocking effect of the trench and the barrier filled with soft
material is more effective than that of the barrier filled with hard material.
