摘　　要：【目的】通过系统的工程地质调查和工程地质特征分析,对重庆市某石灰岩矿高陡边坡的稳定性进行分区评价和分析,以降低露天矿山的地质灾害风险。【方法】采用边坡地质调查的方法,查明各个分区内边坡裂隙的发育特征,绘制岩质边坡的赤平投影图,分析边坡优势岩层层理面倾向和边坡倾向的组合关系,对边坡的稳定性做出定性分析和评价。【结果】结果表明,A区岩质边坡处于较稳定状态,B区发生局部滑塌掉块的可能性大、造成的损失小、危险性中等,C区岩质边坡处于稳定状态,D区岩质边坡处于稳定状态。【结论】评价结果有利于矿山制订科学的治理方案和有效的管理方案,降低边坡的失稳风险,对保障矿山安全生产和生态环境可持续发展具有重要的指导意义。[Purposes]Through systematic engineering geological investigation and analysis of engineering geological characteristics,the stability of a high steep slope in a limestone mine in Chongqing was evaluated and analyzed in different zones to reduce the geological hazard risk of open-pit mines.[Methods]By using the method of slope geological survey,the development characteristics of slope cracks in each zone are identified,and the rock slope projection is drawn in a stereographic projection.The combination relationship between the dominant rock layer bedding plane inclination and the slope inclination is analyzed,and the stability of the slope is qualitatively analyzed and evaluated.[Findings]The analysis results of the stereographic projection show that the rock slope in Zone A is in a relatively stable state;there is a high possibility of local landslides and falling blocks in Zone B,resulting in minimal losses and moderate danger;the rock slope in Zone C is in a stable state;the rock slope in Zone D is in a stable state.[Conclusions]The evaluation results are helpful for the mine to formulate scientific treatment plans and effective management plans,reduce the risk of slope instability,and have important guiding significance for ensuring mine safety production and sustainable development of ecological environment.
