Shunhua ZhouProfessor 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 nfrastructure. 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. Read More Read Less
