矿山开采诱发边坡形变规律分析及控制对策

Analysis of Slope Deformation Law Induced by Mining and Control Countermeasures

以某矿山开采边坡为背景,综合分析了该边坡周边区域的工程地质条件,基于SLIDE软件平台构建了边坡稳定性计算模型,对强降雨及削坡条件下边坡岩土体的稳定性与排水条件下边坡岩土体的稳定性进行对比分析,并对边坡变形发展特点和滑坡的发生机理做出判断。通过对不同边坡模型的计算,明确了以上各条件对边坡稳态的影响,研究结论可以为该边坡的稳定性控制及滑坡预防提供依据。

Taking the mining slope of a mine as the study background,the engineering geological conditions of the of the surrounding area of the slope is analyzed comprehensively. The slope stability calculation model is established based on SLIDE software,the slope stability under the different conditions of heavy rainfall or cutting slope and drainage are conducted comparison and analysis. The development characteristics of slope deformation and occurrence mechanism of landslide are judged.Through calculation of different slope models,the influences of the above conditions to slope stability are analyzed clearly. The above analysis results in this paper provide some theoretical basis for stability treatment and landslide prevention of the slope.
