Abstract
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. Using the three-dimensional discrete element method and considering the influence of different geo-stress environments, the stress field and energy characteristics, the failure characteristics and the rockburst proneness of surrounding rock mass were studied after tunnel excavation, and the following summaries are obtained: When the lateral pressure coefficient is same, the stress and releasable elastic energy distribution characteristics of surrounding rock mass under different buried depths are basically the same. With the increase of the buried depth, the value of the stress and releasable elastic strain energy increase, and the rockburst is more prone. The area where the surrounding rock mass break or rockburst occurs consistent with the area with larger elastic strain energy releasing. The research results can improve the understanding of ruckburst mechanism and provide a reference for rockburst prediction.
