摘　　要：对某高速公路边坡失稳成因进行综合分析,通过方案比选,采用一种坡体内采用圆形抗滑桩,外露部分采用矩形抗滑桩的边坡加固方案。治理方案避免了边坡变形对坡顶房屋产生影响;同时,施工方便、经济有效的特点契合了抢险工程的要求。经过近八年的运营期,边坡整体稳定,验证了该方法的有效性。Based on the comprehensive analysis of the causes of the slope instability of an expressway, through scheme comparison, a slope reinforcement scheme using circular anti-slide piles in the slope body and rectangular anti-slide piles in the exposed part is adopted. The treatment plan has avoided the influence of slope deformation on the house at the top of the slope;at the same time, the characteristics of convenient, economical and effective construction meet the requirements of the emergency project. After nearly eight years of operation, the slope is stable overall and the effectiveness of this method is verified.
