Mechanism Study and Tendency Judgement of Rockburst in Deep-Buried Underground Engineering
Minerals (Basel, Switzerland), 2022 Rockburst is a type of dynamic instability failure phenomenon and frequently brings huge losses to underground engineering projects such as mines and tunnels. In order to explore rockburst mechanisms and predict rockbursts better, relying on the background of Wulaofeng deep-buried highway tunnel, in situ stress measurement was performed using new ...
