    Abstract
  •   Objective  The Tibetan Plateau is one of the most tectonically active regions in the world. The coupled effects of endogenic and exogenic processes result in frequent geological hazards and complex engineering geological problems, posing a significant threat to the geological safety of major engineering projects.   Method  This paper summarizes the application of geomechanics theories in the prevention and control of geological safety risks for major engineering projects, based on over two decades of research conducted on the Tibetan Plateau by our team.   Results  Specific contributions include: (1) The theory of regional crustal stability evaluation was advanced, and a methodology was proposed for investigating and assessing regional crustal stability, engineering geological stability, and site stability; this has been effectively applied to the route selection and site planning of major projects; (2) An engineering geological research framework was established for active tectonic zones, the geohazard effects of active faults were clarified, geomechanical models for high-position landslides were developed, and the combined control mechanism of rock mass structure and special lithology on landslide formation was revealed; (3) Research on rockburst mechanisms in deeply buried tunnels was conducted based on in-situ stress measurements, the characteristics of rockbursts under different tectonic settings were compared and analyzed, and strategies for rockburst prevention and control in high-stress environments were proposed. Building upon the aforementioned research findings, future directions for the innovation of geomechanical theories and their engineering applications are proposed.   Conclusion  The research on the application of engineering geology can further promote the advance of geomechanics and provide new theoretical and technical support for the planning and construction of major national projects, as well as disaster prevention and mitigation.
