摘要/Abstract

摘要： 对平庄西露天煤矿边坡滑移模式进行了分析，得出软弱层面是控制滑坡的主因。针对抗滑桩埋设深度受限、不能对边坡深部的潜在软弱层滑移面进行控制而形成随深增加潜在滑移体积累的特点，对采用预应力长锚索加固深部弱层面的方式进行分析研究，结果表明采用预应力锚索加固可以明显提高岩体强度，消除沿弱层面滑移的安全隐患。在矿山的实际应用证明，预应力锚索加固深部弱层面效果良好，达到预期结果。

Abstract: Through analyzing the landslide pattern of the slope in West Open Pit Coal Mine of Pingzhuang, a conclusion can be drawn that the weak interfaces is the main controlling factor of landslide. Considering the depth of anti-sliding pile is limited so that it can not control the potential deep-stated weak interfaces which will accumulate the potential sliding mass with the increase of mining depth, so another reinforcement method, using prestressed anchor rope to reinforce the deep-stated weak interfaces, is analyzed. The results show that this method can improve the strength of the whole rock mass obviously and erase the incipient fault of slipping along the weak interfaces. The practice of the mining area also proves that the prestressed anchor rope reinforcement is in good working order and meets the expectant result.

Key words: pattern of landslide, prestressed anchor rope, numerical analysis
