| 摘 要： | 岩爆是高地应力条件下完整脆性硬质围岩失稳的一种表现型式,岩爆烈度如何影响围岩类别尚不清楚,探索岩爆与围岩分类的关系,对准确判别高地应力条件下的围岩类别有着重要意义。本文以某深埋隧洞围岩分类为依据,对我国水利水电地下洞室围岩分类中岩爆烈度与围岩类别的关系、岩爆判别指标的选取等问题进行了探讨。

| Abstract: | Rock burst is a type of instability of hard intact surrounding rock in the condition of high field stress.The relations between rock burst intensity and surrounding rock rating are not known clearly.It is very important to find the relations between rock burst and surrounding rock classification in the high field stress.In this paper,some problems such as the relations between rock burst intensity and surrounding rock rating,the choice of the criteria of rock burst for water resources and hydroelectric underground excavation in China are discussed.An example for surrounding rock mass classification of a deep-buried tunnel in China is given.A suggestion that the relations between rock burst intensity and surrounding rock rating should be increased in national correlation criterion is proposed. |
