| Abstract: | As one of the geological hazards,rockburst is often met in underground engineering. In this paper, the basic laws of rockburst in the tunnel of Erlang Mountain road are summarized with more than 200 rockburst incidents recorded during tunnelling. Three effective methods for forecasting rockburst are also discussed. They are geology supertime forecasting,σ θ /R b judging and rockburst critical depth forecasting. |
