| Abstract: | Rock burst is normal in high geostress area, as a result of rock mass failure. Located in middle - high geostress area, the Laxiwa hydropower project has a great deal of rock bursts during tunnel excavation. Most of the rock bursts are slight, and some are moderate in locals, which have a certain influence on tunnel stability and safety. Effective prevention measures have been taken. |
