摘　　要：以某公路修建过程中发生的滑坡为研究对象,通过详细的调查研究,明确滑坡的成因为特殊的地形地质条件下公路边坡开挖临空由降雨作用诱发。结合岩土体物理力学参数反演结果对滑坡稳定性现状进行计算分析,认为滑坡会发生进一步滑移从而产生更大规模滑坡,按应急抢险要求,提出了以抗滑挡墙支挡及完善坡面截排水措施的综合处治方案,治理效果良好。In this paper,the landslide occurred in the construction process of a highway is researched,through detailed investigation and research,it is clear that the landslide is caused by rainfall when the slope is excavated under special topographic and geological conditions.The inversion results of the physical and mechanical parameters of rock and soil are used to calculate and analyze the current stability of the landslide,according to the emergency rescue requirements,it is proposed to support the anti-slide retaining wall and improve the slope surface,a comprehensive treatment scheme of anti-sliding retaining wall and improvement of slope interception and drainage measures is put forward,and the treatment effect is well.
