| 摘 要： | 文章分别分析了隧洞围岩的宏观结构因素（结构面发育情况，结构面与硐室或隧道轴线的关系及与最大主应力的关系等）及微观结构因素（岩石矿物颗粒的排列、颗粒间的联接以及粒间的空隙特征等）对岩爆的影响。分析表明，围岩的宏、微观结构与岩爆发生及发生的强烈程度有紧密的关系。在实际工程中，这一认识对岩爆问题的正确评价无疑是十分有益的。

| Abstract: | The paper analyses the influence of the wall-rock's macroscopic structure factors such as the developmental state of the structural surface,the relation between the structural surface and the axis of the tunnel and the relation between the structural surface and the maximum principal stress to the rockburst.The paper also analyses the influence of the wall-rock's microscopic structure factors such as the arrangement of the mineral particles,the junction between the particles and the void features between the particles on the rock-burst.The above analysis indicates that the wall-rock's macroscopic and microscopic structures closely related not only to whether the rockburst happens but also to its happening intensity.In actual engineering,this opinion is useful to proper evaluation of rockburst. |
