Dynamics of Rail Transit Tunnel Systems
Auteur : Zhou Shunhua
Dynamics of Rail Transit Tunnel Systems develops the dynamic theory of a rail transit tunnel system and provides research methods for the evaluation of long-term settlement of rail transit tunnels in soft soil, the service performance of tunnel structures, and the characterization of environmental vibration induced by trains. In recent years, a large number of rail transit tunnels have been constructed and put into operation, particularly in China. To evaluate the time-dependent degradation of tunnel structures and train-induced environmental vibration, a reliable model must be established to determine the dynamic response of a vehicle-track-tunnel-soil system, hence the introduction of this timely resource.
