Abstract

With the deepening development of underground space, the issue of rockbursts in tunnel engineering has become increasingly prominent, severely affecting construction safety. This study employs numerical simulations, and experimental testing methods to investigate the rockburst characteristics in drilled-blasted tunnels under different surrounding rock categories. The results indicate that rockburst energy is primarily concentrated around the crown, the invert, and the surrounding rock near the tunnel walls. The initial support is within the limit bearing capacity range, and no damage to the initial support was observed due to rockbursts. Based on these findings, measures to strengthen rockburst monitoring and inspection are proposed. This research provides valuable theoretical and practical guidance for the prediction, prevention, and control of rockbursts in tunnel engineering.
