南疆铁路K230段冻土区滑坡泥石流勘察整治

Survey and remediation of landslides and debris flows in the frozen area along the southern Xinjiang Railway K230

本文结合南疆铁路K230滑坡、泥石流的勘察与治理工程设计,深入分析了冻土地区滑坡的成因,滑面特性,泥石流产生的原因等,进而针对原因分析提出了采用对原地层扰动较小的锚索框架治理滑坡、采用拦挡坝治理泥石流,且采用保温盲沟疏排地下水的综合治理措施。该段地质病害的成功治理,对类似冻土地区地质病害的勘察与整治具有一定的借鉴意义。

Based on exploration and engineering design of the landslides and debris flows in the Section K230 of the Southern Xinjiang Railway,the paper deeply analyzed the forming process of landslides and debris flows in the frozen area.Thus,it proposed an anchor-cable frame engineering measures for landslides for the least disturbance to the original soil,as well as block dams and insulated blind drainage ditches for debris flows.The practical engineering showed that the proposal was successful to stable the soil,which would be helpful for the same geo-hazards control in similar regions.
