【摘要】 地下洞室是危害露天矿边坡稳定性的重要因素 ,其分布情况更是评价露天矿边坡稳定性的重要条件。通过分析地下洞室的应力分布情况 ,利用极限平衡法及格里菲斯强度理论 ,讨论并研究了地下洞室对露天矿边坡稳定性的影响 ,发现地下洞室的直径和其走向与整体边坡走向的关系对露天矿边坡稳定性的影响很大更多还原

【Abstract】 The underground chamber is the important factor damaging the stability of the open-pit mine slope. And its distribution is still more the important factor evaluating the stability of open-pit mine slope. Through analyzing the stress distribution of underground chamber, by using limit equilibrium method and the Griffth failure theory, the effect of underground chamber on the stability of open-pit mine slope is discussed and researched. It is found that the diameter of underground chamber and relation between the strike of this chamber and strike of integral slope have great effects on the stability of open-pit mine slope.更多还原
