摘要
以某铅锌矿强分化千枚岩体滑坡治理工程为例,采用极限平衡法对三种不同工况下滑坡体稳定性和推力进行分析研究,以此为指导提出了“桩板墙+格构梁+抗滑锚索”滑坡治理总体方案;现场实践效果表明,治理方案是可行的,施工完成一年多来,滑坡体监测点位移明显变小,回填裂缝无扩展,滑坡治理效果良好;可为类似矿山滑坡治理提供经验借鉴。
Taking as an example for the landslide control project of a strong-differentiated phyllite rock mass in a lead-zinc mine,the stability and thrust of the landslide under three different working conditions are analyzed and studied by using the limit equilibrium method,guided by this,we put forward the overall landslide control scheme which is"pile-sheet wall+lattice beam+anti-slide anchor cable".The field practice results show that the control scheme is feasible,over the past year,the displacement of landslide monitoring points has obviously decreased,the backfill cracks have not expanded,and the landslide treatment effect is good,which can provide experience for similar mine landslide treatment.
