摘要
本文将在水电洞室、交通隧洞、矿山坑道岩体或矿体中发生的急剧猛烈释放弹性变形能的动力破坏现象统称为岩爆。在讨论岩爆与其他动力现象之间的区别和岩爆含义基础上,按照地应力作用方式,将其分为水平应力型、垂直应力型以及混合应力型3种主要类型,并分别讨论了各类岩爆的具体特征以及防治措施。
This paper deals with the sudden - violent dynamic failure through the releasing of energy in clastic deformation within the rock masses of hydropower tunnels, underground power houses and traffic tunnels, or with in the mine masses of the mining pits. The dynamic failure is called rock-burst. Based on the discussion of rockburst definition and the differences among rockbursts and other dynamic failures of the rock masses, and also according to the action pattern of the earth stress,three types of rockburst are classified, i.e. the horizontal stress type, the vertical stress type and the mixed stress type. Both the characteristics and the treatment methods of the different types of rock-burst are discussed in the latter part of this paper.
