摘　　要：通过数值模拟方法研究了倾斜锚固桩在加固含软弱夹层边坡中的稳定性影响,探讨了软弱层角度及桩倾斜度对桩身位移及内力的影响规律。研究发现,软弱层角度和桩倾斜度对边坡稳定性具有显著影响。软弱层角度的增大通常导致桩身位移和内力增加,而桩倾斜度的调整则能有效控制桩身位移和内力,特别是当桩倾斜度调整至30°时,既能优化边坡的稳定性又能降低设计成本。通过对比分析不同倾斜度及桩长的桩体设计,提出了在保证边坡稳定性的同时,通过最小化内力峰值以降低设计成本的优化方案,为实际工程提供了理论依据和参考。This study investigates the stability impact of inclined anchoring piles in reinforcing slopes containing weak inter-layers through numerical simulations,focusing on how the angle of these layers and the pile inclination impact pile displace-ment and internal forces.It reveals that both the weak layer angle and pile inclination markedly influence slope stability.An increase in the weak layer angle generally results in heightened pile displacement and intermal forces.Conversely,optimizing the pile inclination,particularly to 30°,can control these factors effectively,enhancing slope stability and lowering design costs.By analyzing various inclinations and pile lengths,the paper proposes an optimization strategy that reduces peak inter-nal forces while maintaining slope stability,offering a theoretical foundation and practical guidance for engineering applica-tions.
