摘要
针对滑坡风险评价及边坡加固问题,以乌山铜钼露天矿为工程背景,构建了包含多种滑坡类型的滑坡案例库,利用工程类比法与相似度匹配得到乌山铜钼矿南帮的滑坡预警阈值,同时分析了高风险区域的边坡加固效果.研究结果表明,乌山铜钼矿南帮的潜在滑坡与抚顺西露天矿顺层滑坡的相似度达到80.9%,利用抚顺西露天矿顺层滑坡的后验性预警指标来预警乌山铜钼矿南帮的潜在滑坡具有可行性,并成功预测了一次小型滑坡;经分析,锚索可有效抑制该边坡的变形,加固效果良好.
Abstract
Aiming at the problem of landslide risk assessment and slope reinforcement,taking Wushan Copper-Molybdenum Open-pit Mine as the engineering background,a landslide case library con-taining various landslide types was constructed.The landslide warning threshold of the south slope of Wushan Copper-Molybdenum Mine was obtained by engineering analogy method and similarity matching,and the slope reinforcement effect in high-risk areas was analyzed.The results show that the similarity be-tween the potential landslide in the south of Wushan Copper-Molybdenum Mine and the bedding landslide in Fushun West Open-pit Mine is 80.9%.It is feasible to use the posterior warning index of the bedding landslide in Fushun West Open-pit Mine to warn the potential landslide in the south of Wushan Copper-Mo-lybdenum Mine,and a small landslide is successfully predicted.After analysis,the anchor cable can effec-tively inhibit the deformation of the slope,and the reinforcement effect is good.
