Abstract
This paper presents a study of the efficiency of isolated concrete blocks as vibration mitigation measures for railway-induced ground-borne vibration problems in subway metro tunnels. The study is performed numerically, using a 2.5D FEM-BEM model of the tunnel-soil system, a semi-analytical model of the track and a rigid multibody model of the vehicle. This comprehensive model of the train-track-tunnel-soil system is used to simulate the vibration response at the tunnel wall due to train traffic...
