    摘要:

    为探究不同层理倾角对岩体岩爆倾向性的影响,以武九高速土建工程高楼山隧道的层理灰岩为研究对象,通过室内单轴加载与加卸载试验,结合弹性应变能岩爆指标、临界埋深岩爆指标、陶振宇岩爆指标和Russense岩爆指标对不同层理角度的岩样进行了岩爆倾向性综合分析。结果表明:不同岩爆指标的判别结果之间存在一定差异;层理角度对岩爆倾向性有显著性影响,当层理角度为60°时岩爆倾向性最高,层理角度为45°时岩爆临界埋深最浅;基于多重判据的岩爆倾向性判别法为在具有层理结构岩体的地下工程中进行岩爆灾害的预测预报提供了有益参考。

    Abstract:

    In order to explore the influence of different bedding angles on rockburst proneness of the rock mass, taking the bedding limestone of Gaoloushan tunnel as the research object, through indoor uniaxial loading and unloading tests, combined with elastic strain energy rockburst index, critical buried depth rockburst index, Tao Zhenyu rockburst index and Russense rockburst index, the rockburst tendency of rocks with different bedding angles was comprehensively analyzed. The results show that: there are some differences among different rockburst indexes; the bedding angle has a significant influence on the rockburst proneness. When the bedding angle is 60 ° the rockburst tendency is the highest, and when the bedding angle is 45 ° the rockburst critical buried depth is the shallowest; the method based on multi-criteria can be used to predict the rockburst disaster of underground engineering with bedding structure rock mass, which provides a useful reference for engineering practice.
