Dr. Shuai Li’s research primarily focuses on geotechnical engineering, with a particular emphasis on civil engineering disaster prevention and mitigation. His work investigates the mechanical behavior of rock masses under dynamic conditions, especially during processes like shield tunneling, and the associated surface deformation. Dr. Li has contributed significantly to the development of finite element analysis (FEA) simulations to study the stability of underground structures, such as subway tunnels. His research also explores rock mechanics, including mixed-mode fracture characteristics, stress relaxation in sandstone, and the effects of dynamic disturbances on the creep behavior of rocks. In addition, he is involved in innovative testing methods for rock permeability and rheological relaxation, contributing to the design and analysis of geotechnical engineering projects. Dr. Li’s work is vital for improving the safety and stability of infrastructure in complex geological environments, with applications in urban tunneling, mining, and civil construction.
