Tóm tắt

The occurrence of rockbursts is closely related to the stress environment and structural characteristics of rock mass. The Lalin Railway Tunnel in China was taken as a case study, a modified method for evaluating rockburst grades was proposed based on the ratio of rock mass strength to maximum tangential stress at the tunnel wall, and the accuracy of this method was also validated. Furthermore, a three-dimensional numerical model of tunnel excavation was established using FLAC
