西南高原向丘陵过渡斜坡地带滑坡机理与稳定性评价

滑坡区域虽然平缓，但通过调查分析发现，其地形、地层、物质条件决定了该区形成滑坡的必然性；通过钻探与变形监测分析判定滑带位于岩土分界面上。采用综合勘察手段查清了滑坡的结构特征与形成机制，确定了滑坡各区影响范围。结合滑坡特征、计算结果及治理目标，提出了支挡和排水相结合的综合治理措施，治理后，经过两个水文年监测表明治理效果显著。

Landslide Mechanism and Stability Evaluation in the Southwest Plateau to Hilly Transition Slope Zone

Although the landslide area is gentle, the inevitability of landslide formation in this area is determined by investigation and analysis of its terrain, stratum and material conditions. Through drilling and deformation monitoring analysis, it is determined that the sliding zone is located on the geotechnical interface. The structural characteristics and formation mechanism of the landslide are found out by means of comprehensive investigation, and the influence range of each area of the landslide is determined. Combined with the landslide characteristics, calculation results and treatment objectives, a comprehensive treatment measure combining retaining and drainage is proposed. After comprehensive treatments, through two hydrological years of monitoring, the result shows that the treatment effect is remarkable.
