摘　　要：抗滑桩是边坡加固常用的技术手段,准确分析抗滑桩加固边坡的稳定性对确保工程安全及服役性能至关重要。结合高速公路工程实例,对病害段高边坡进行抗滑桩设计和验证。基于极限分析模型,建立了抗滑桩加固边坡的失稳机制。构建了功率平衡方程并与强度折减法相耦合,以迭代优化求解出了抗滑桩加固边坡的安全系数。对抗滑桩的参数进行了计算分析,给出了桩位和桩径的推荐取值,并以工程实例验证了提出方法的适用性,可为抗滑桩加固边坡的初步设计提供参考。Anti-slide piles are essential for reinforcing slopes on highways and railways.Accurate analysis of slope stability with these piles is crucial for safety and performance.This paper presents a highway engineering case to design and verify anti-slide piles on a high slope.Using limit analysis,the failure mechanism of a pile-reinforced slope is established.A power balance equation is constructed,coupled with the strength reduction method,and the safety factor is solved through iterative optimization.Parameters of anti-slide piles are calculated,and recommended values for pile positions and diameters are provided.An engineering example demonstrates the method's applicability,serving as a reference for the preliminary design of anti-slide pile reinforced slopes.
