研究目的:采用离散单元法对几种常用的岩爆控制方法进行了数值模拟，旨在为岩爆防治设计提供理论 依据,确保隧道施工安全。
研究结论:数值模拟结果表明:注水围岩软化法是通过降低岩石弹性模量达到减少围岩内切向应力的目 的，只适用于吸水性较强的围岩;而钻孔应力释放法是通过钻孔实现围岩内切向应力向内部围岩转移，适用于 弱~较强岩爆;超前应力解除爆破法是通过超前爆破,更大程度地实现围岩内切向应力向内部围岩转移，适用 于强岩爆洞段。

Research purposes： This paper carried out simulations of several often used anti-rockburst methods by using the discrete element method in order to provide theoretical basis for anti - rockburst design and ensure the safety of tunnel construction.
Research conclusions ：The numerical simulation results show that the rock softening method by spraying water onto the rock surface is to achive the stress reduction in surface rock by reducing the rock deformation modulus, and thus suitable only for rock mass with strong water absoption. The stress release method by drilling holes is to achieve stress migration from surface rock to inner rock by drilling holes on the walls, and more suitable for weak to stronger rockbursts. The stress release method by blasting behind the work face is，however, to achieve more tangential stress transferring from surface rock to inner rock by conducting advanced blasting, and thus most applicable to strong rockbursts.
