Aiming at the mountain landslide on left side of K44 + 650 ~ K44 + 850 section of Naxi-Qianchuan Expressway, this paper introduces profile and basic features of the landslide and analyzes influencing factors and generation mechanism of the landslide. The indoor test results and inversely calculated landslide parameters are used to analyze stability of the landslide, and the thrust of landslide and the effect after treatment by anti-slide piles are calculated. The result shows that the landslide calculating parameters are reasonable, the treatment by means of 2 rows of anti-slide piles is appropriate and the landslide after treatment is stabilized.%针对四川省纳黔高速公路K44+650~K44+850段左侧山体滑坡,介绍滑坡概况及其基本特征,分析滑坡的影响因素及成因机制。利用室内试验结果和反算的滑坡体参数分析边坡的稳定性,并计算滑坡推力以及采用抗滑桩处治后的效果。结果表明,滑坡计算参数合理,采用2排抗滑桩的处治方式得当,处治后滑坡稳定。
