Application and design optimization of inclined anchoring piles for enhancing the stability of slopes with weak interlayers
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 internal 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.
