Study on Rockburst Proneness of Deep Tunnel Under Different Geo-Stress Conditions Based on DEM

Rockburst seriously threaten the economic benefits and construction safety of deep tunnel. Rockburst prediction is one of the key scientific issues in rockburst research. In this paper, the elastic strain energy is regarded as the inherent power of rockburst. A multi-factor rockburst criterion is established which consider the properties of rock, the intactness of the rock mass and the releasable elastic strain energy of surrounding rock mass....
