摘　　要：为研究三排微型桩组合结构加固边坡时桩体倾角对力学响应的影响,文中针对均质黏性土边坡工程,采用数值模拟软件对5种不同加固方案下不同桩身倾角的加固效果进行模拟。结果表明桩身倾斜较竖直布置可显著提高加固效果,最大可降低边坡水平位移75%以上。不同方案的最佳倾角范围不同,其中方案3在倾角30°~40°时加固效果最佳。实际工程应根据工程条件灵活选择方案以实现有效加固。To investigate the impact of pile inclination on the mechanical response of a three-row micropile composite structure for slope reinforcement,this study focuses on a homogeneous cohesive soil slope.Numerical simulation software was used to model the reinforcement effects under five different reinforcement schemes with varying pile inclinations.The results indicate that inclined piles significantly enhance the reinforcement effect compared to vertical piles,reducing horizontal slope displacement by more than 75%at maximum.The optimal inclination range varies among different schemes,with scheme 3 achieving the best reinforcement performance at an inclination of 30°~40°.In practical engineering applications,reinforcement schemes should be selected flexibly based on project conditions to ensure effective stabilization.
