摘　　要：堆填土滑坡自身地质条件复杂,外部环境变化大,最不利滑动面的确定十分复杂。结合某道路K9处堆填土滑坡治理工程,分析了滑坡的变形特征和形成原因;运用理正岩土软件搜索出滑坡的最不利滑面;然后利用最不利滑面的信息,计算滑坡在不同工况下支挡工程所需的抗滑力,并提出相应的治理措施。The geologic condition of filled soil landslide is complex,the external environment change is great,and it＇s quite complicated to determine the most unfavorable sliding surface. Combining the filled soil landslide treatment at K9 of a road,deformation characteristics and formation cause of landslide were analyzed. Lizheng geotechnical software was adopted to search the most unfavorable sliding surface of the landslide. And then the most unfavorable sliding surface information was used to calculate the anti-slide force for supporting the project under different conditions and corresponding treatment measures were put forward to achieve better effects.
