摘　　要：以武汉市青龙山边坡为研究对象,对该边坡的稳定性系数进行了计算,分析了边坡的变形破坏机制和变形破坏模式,根据分析结果和边坡实际情况确定了“坡面整形+格构梁锚杆+排水措施+坡面绿化+监测”的边坡治理方案,并对治理方案进行了详细介绍。对边坡治理后的稳定性系数进行了计算,结果表明治理后的边坡在暴雨工况下处于稳定状态。边坡监测结果显示,边坡的竖向累计沉降量和沉降速率均在预警范围内。经过治理,边坡稳定性得到了大幅提升,治理效果良好,可为类似边坡的治理方案设计提供参考。A slope of Qinglong Mountain in Wuhan City is presented in this paper as case history of the slope stability analysis.The factor of safety of the slope is analyzed.The deformation,the damage mechanism,and the damage mode of the slope are e-valuated.The slope management plan of"slope shaping+lattice beamed ground anchors+drainage measures+slope vege-tation+monitoring"was utilized based on the analytical results.The actual conditions of the slope,the management plan and the slope remediation plan are introduced in detail in this paper.The factor of safety against the mitigation slope stability is esti-mated.The results showed that the treated slope is in a stable state under heavy rainfall conditions.The slope monitoring re-sults show that the vertical accumulated settlement and settlement rate of the slope are within the tolerable range.After the treatment,the stability of the slope has been greatly improved.This study can provide a reference for the reinforcement design of similar slopes.
