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.
- Provides full theoretical background to help the reader gain an in-depth understanding of the various methods used for dynamic analysis of a rail transit tunnel system
- Develops the dynamics theory and method of a rail transit tunnel system under the context of challenging engineering problems
- Presents methods for analyzing the dynamic responses of rail transit tunnel-soil systems
- Looks at problems that need to be solved in the future and proposes potential directions for future research

Shunhua Zhou
Professor in the College of Transportation Engineering at Tongji University, China. He has a long professional career in engineering mechanics and advanced applied engineering technology related to the construction and maintenance of railway transit infrastructure. His research includes the theory and engineering practice of excavation, evaluation of settlement and deformation of railway transit structure, and vibration reduction of railway transit systems. His research team developed a new method of tunnel systems dynamics for the deformation analysis of railway transit structures, and based on this a systematic approach for ground deformation control in the construction of tunnels across operational railways. Using this approach, a tunnel was successfully built for the first time beneath an operating high-speed railway, with a speed of 300km/h.
