In recent years, a large number of rail transit tunnels have been constructed and put into operation, particularly in China. Internationally, this is also an area of expanding interest. 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. Such a model should be able to characterize various mechanisms of coupled vibration and to provide guidance to engineers for measures to mitigate various problems. 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. Provides full theoretical background to help the reader gain an in-depth understanding of various methods used for dynamic analysis of a rail transit tunnel systemDevelops the dynamics theory and method of a rail transit tunnel system, under the context of challenging engineering problemsPresents methods for analysing the dynamic responses of rail transit tunnel-soil systemsLooks at problems that need to be solved in the future, and proposes potential directions for future research INDICE: 1.
