Fei Liu has built a strong research profile centered on rock mechanics, rockburst mechanisms, microseismic monitoring, and the stability of deep underground structures, combining extensive project experience with advanced analytical approaches to understand failure behavior in complex geological environments. His work spans true-triaxial unloading conditions, microseismicity evolution, jointed rock mass behavior, and deep excavation performance, contributing valuable insights into predicting and mitigating rockburst hazards in tunnels, hydropower stations, metro systems, and large-scale water conveyance projects. Through projects such as the study of rockburst initiation mechanisms under high-stress unloading, catastrophic strainburst failure processes, and multi-source precursory signatures, he has advanced both theoretical understanding and engineering applications by integrating discrete element modeling, field monitoring, and data-driven analysis. His leadership in projects funded by provincial foundations, national engineering research centers, and industry commissions highlights his capability to translate scientific concepts into practical solutions, particularly in supporting excavation safety and developing early warning technologies for high-risk underground environments. His published work covers failure characteristics of jointed rock, observed performances of deep excavations, collapses in large tunnels, and microseismic monitoring-based rockburst prediction, reflecting a consistent focus on coupling mechanical behavior with early-warning indicators. By linking numerical simulation results with real-world monitoring data, he contributes to improving the reliability of hazard prediction models, optimizing excavation strategies, and enhancing risk-control frameworks in deep engineering construction. Across his research trajectory, he continues to explore the dynamic behavior of rocks, precursory energy evolution before failure, and innovative monitoring techniques that enhance the safety and resilience of underground infrastructure. This integrated research approach positions him at the forefront of rockburst mechanism studies and deep engineering risk assessment, driving ongoing advancement in underground construction safety and rock mechanics research.
