摘要
为合理分析边坡稳定性并对失稳边坡进行有效治理,以红沙泉露天煤矿老外排土场为工程背景,结合边坡地质条件和岩石力学参数,基于极限平衡理论运用Geo-studio软件和数值模拟软件FLAC3D分析边坡的滑坡模式、应力状态和位移情况,并对研究边坡进行治理。研究结果表明:边坡的滑坡模式为圆弧形滑动,剖面安全系数为0.865,最大位移为3.94 m,2种分析结果表明边坡是极不稳定的;对于边坡采用毛石混凝土挡土墙的方式进行支护,经验算治理后的边坡满足稳定性要求。
In order to reasonably analyze the slope stability and effectively control the unstable slope,taking the old external dump of Hongshaquan Open-pit Coal Mine as the engineering background,the article combines the slope geological conditions and petrological parameters,uses Geo-studio software based on limit equilibrium theory and numerical simulation software FLAC3D to analyze the landslide mode of the slope,stress state and displacement,and control the slope.The results show that the slip state of the slope is circular arc sliding,the section safety factor is 0.865,the maximum displacement is 3.94 m.The slope is extremely unstable;for the slope of the use of stone concrete retaining wall way to support the experience of the slope after the slope to meet the stability requirements.
