摘要

As tunnel projects delve deeper, rockburst accidents occur frequently, posing a serious threat to people and equipment safety. The mechanism of rockburst has not been studied clearly, which makes it impossible to predict rockburst accurately. Therefore, it is essential to implement corresponding preventive measures to mitigate the risk of rockburst. Numerical simulation has emerged as one of the important methods to study rockburst because of its advantages of safety, effectiveness, and low cost. Based on visual analysis, this paper discusses the current situation and progress of numerical simulation in rockburst, it elucidates the primary applications and limitations of numerical simulation in understanding rockburst mechanisms, predicting and preventing such incidents. Additionally, it introduces continuous methods, discrete methods, and hybrid methods, comparing and analyzing their advantages and disadvantages. Furthermore, various mechanical behaviors of rock masses in simulating rockburst are discussed. The numerical manifold method and peridynamics are highlighted as having better simulation results. Finally, the unsolved problems in the application of numerical simulation in rockburst are put forward, and the breakthrough of numerical simulation under the dynamic load of rock mass and the development of intelligent hybrid simulation prospects.
