In-situ stress characteristics and rockburst prediction for a tunnel in a high in-situ stress environment

Frontiers in Earth Science
As the main source of pressure around tunnel rock masses, in-situ stress must be thoroughly understood to accurately predict the potential for rockburst events, especially in high-stress construction environments.
