摘　　要：为实现公路边坡的合理防治,文中先分析了不同支护措施在边坡防治中的适宜性,筛选出最优防治措施,再进一步通过传递系数法、变形预测等手段开展边坡防治后的稳定性评价,以验证防治措施的合理性。经分析,K32+386-K32+509段边坡的防治方案主要有3类,即方案一“抗滑桩”、方案二“锚杆”、方案三“抗滑桩+锚杆”,且经筛选,方案三最为适合该段边坡防治。在边坡防治后,边坡稳定性及变形控制始终满足要求,充分验证了“抗滑桩+锚杆”在该段边坡防治中具有较高的适用性。In order to achieve reasonable prevention and control of highway slopes,this article first analyzes the suitability of different support measures in slope prevention and control,selects the optimal prevention and control measures,and further conducts stability evaluation of slope prevention and control through transfer coefficient method,deformation prediction and other means to verify the rationality of prevention and control measures.After analysis,there are three main types of slope prevention and control plans for the K32+386~K32+509m section,namely Plan 1 "anti slip pile",Plan 2 "anchor rod",and Plan 3 "anti slip pile+anchor rod".After screening,Plan 3 is the most suitable for slope prevention and control in this section.After slope prevention and control,the stability and deformation control of the slope always meet the requirements,thus fully verifying the high applicability of "anti sliding pile+anchor rod" in slope prevention and control in this section.
