【摘要】 地下硐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,通过分析地下硐室的应力分布情况熏利用极限平衡法及格里菲斯强度理论熏讨论并研究了地下硐室对露天矿边坡稳定性的影响熏发现地下硐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 cavern is the one of important factors that damages the stability of the pit slope. And its distribution is the important factor that evaluates the stability of pit slope. With analyzing the stress distribution of underground cavern based on limit equilibrium method and the Griffth theory of strength, the affection of underground cavern for pit slope is discussed and researched, and found out that the diameter and strike of underground cavern greatly affected the stability of pit slope.更多还原
