开展矿山边坡稳定性分析对识别矿山地质灾害隐患及评估边坡治理措施有效性具有重要意义.以新疆乌鲁木齐市米东区绍兴砂场废弃采砂矿山边坡为例,针对矿区内边坡A及边坡B进行研究.采用Midas GTS NX岩土分析软件有限元强度折减法对边坡进行模拟计算,分析恢复治理前后矿山边坡的稳定性.结果表明,应用Midas GTS NX软件对边坡进行数值模拟分析,所得模拟结果科学直观,在边坡稳定性分析中表现出较好的效果;边坡A经工程措施治理后,稳定性系数明显增大,x轴方向位移量减小了93.9％,最大剪应变分散在各分级台阶的坡脚处,减小了95.5％,潜在滑移面消失,边坡达到稳定状态;通过削高填低、坡脚压实、削坡分级及排水工程等工程措施治理边坡,可有效增加边坡稳定性,消除边坡地质灾害隐患.
Slope stability analysis of abandoned mine slopes based on Midas GTS NX
Performing stability analysis of mine slopes is of great significance for identifying mine geological hazards and evaluating the effectiveness of slope management measures.Taking the abandoned sand mining slope of Shaoxing Sand Field in Midong District,Uru-mqi City,Xinjiang as an example,this study focused on slope A and slope B within the mining area.The finite element strength reduc-tion method of Midas GTS NX geotechnical analysis software was used to simulate and calculate slopes,and the stability of the mine slope before and after restoration and treatment was analyzed.The results showed that applying Midas GTS NX software for numerical simulation analysis of slopes,the simulation results obtained were scientific and intuitive,showing good performance in slope stability a-nalysis;after the implementation of engineering measures on slope A,there was a significant increase in the stability coefficient,addi-tionally,there was a 93.9％reduction in displacement along the x-axis,and a 95.5％reduction in the maximum shear strain at the foot of each graded step.These measures led to the disappearance of the potential slip surface,ultimately resulting in a stable slope;manag-ing slopes through engineering measures,such as high cuts,low fills,foot compaction,cut slope grading,and drainage works,effectively enhanced slope stability and eliminated geologic hazards on slopes.
