Abstract

The study of rockburst criterion is one of the most critical scientific problems in the rockburst research, and it is also the key to predict the occurrence of rockburst. Firstly, based on energy principle, rock strength and overall failure criterion, the classification evaluation system of rockburst intensity of rock under compression and tension is established. Secondly, the accuracy and applicability of some typical rockburst engineering cases in China are tested by using the existing classical rockburst criterion and the rockburst proneness criterion proposed in this study. Finally, based on the No.4 diversion tunnel of Jinping Ⅱ hydropower station, the secondary development of 3DEC numerical simulation software is carried out by using FISH language programming, and the result analysis is carried out on the incubation mechanism and evolution law of rockburst geological disasters in deep underground engineering under three-dimensional stress conditions. The results show that the criterion comprehensively considers all kinds of stress state of surrounding rock unit, and reflects the integrity, mechanical, brittleness and energy storage factors in the process of rockburst initiation. Three grading thresholds (2, 11 and 110) are proposed for the four grades of no, weak, moderate, and intense rockburst. The rockburst proneness criterion based on energy principle is used to predict and evaluate the typical rockburst cases, the results of which are basically consistent with the actual situations of rockburst, and has good effectiveness and engineering applicability. The research results provide a new approach for accurately predicting the rockburst proneness of deep underground engineering.
