摘要
石宝露天铁矿西北区A区边坡发生了大面积整体下滑,对生产造成了严重影响。通过现场调查研究,由于贯穿该区内的一条F16大断层以及两条优势节理J1、J2交互作用影响导致边坡失稳,形成滑坡,因此提出了削坡减载的治理措施。通过FLAC3D数值模拟分析验证,最终得出了外推32m的削坡治理方案,对边坡治理具有一定的参考意义。
Large-area landslides occur in area A,the northwest in Shibao Iron Mine.It causes serious influence on production.Through filed survey,main reason is the interaction between a big fault F16 and two joints J1 and J2 in the slope.Thus the control measures including cutting slope and reducing load are put forward,through analysis verification using FLAC3D numerical simulation.The treatment scheme with outside push 32 meters is concluded,which has certain references for slope treatment.
