由于西藏地区的生态环境较为脆弱，在多因素耦合作用下，该地区的矿山滑坡较为常见。因此其滑坡机理与预防措施值得深入研究，以便对其进行预防和治理。该文首先对西藏某矿区牵引式坡积土质滑坡进行了概况介绍，分析了滑坡机理及主要影响因素;然后针对该滑坡变形特征制定了支护系统+排水系统+回填土反压的治理措施;最后对治理预期效果进行了分析。结果表明，治理后的滑坡处于稳定状态，可为牵引式坡积土质滑坡治理提供思路，具有一定的借鉴作用。

Due to fragile ecology of Xizang area,mine landslides in this area are common under the coupling effect of multiple factors. Therefore the landslide mechanism and preventive measures of such landslides are worthy of in-depth study to facilitate their prevention and control. Firstly,the paper introduces the general situation of the traction-type colluvial soil landslide in a mining area of Xizang and analyzes the landslide mechanism and main influencing factors. Then,control measures of support system + drainage system + backfill are formulated based on the deformation characteristics of the landslide. Finally,an analysis is conducted on the expected effects of the control. Results show that the landslides after control are in stable state,which can provide ideas for the control of traction-type colluvial soil landslides and have reference value.
