在门架桩基础上发展起来的 h 型抗滑桩具有优越的抗滑性能和经济优势，但其结构机理和抗滑能力还需进一步深入研究，为此，以桩土作用为出发点对 h 型桩的结构受力形式进行分析，揭示其受力规律。以滑坡实例为研究对象，采用 FLAC3d 软件，对滑坡进行稳定分析。建立 h 型桩的三维模型，掌握 h 型桩对边坡稳定性影响效应，明确 h 型桩的桩身位移和弯矩的分布情况。最后同门架式桩进行对比，显示 h 型桩更具优良的支挡性能，为此类结构的推广应用提供技术参考。%Based on portal pile,h pile has excellent anti-slide performance and economic superior-ity,however its mechanism and anti-slide performance still need research.Therefore,its stress and mecha-nism is simulated based on pile-soil interaction.FLAC 3d is used in landslide,the stability of slope is evalu-ated.Through establishing 3D model,h pile‘s influence on the slope stability and the distribution of pile displacement and bending moment is revealed.Compared with portal pile,h pile is a more useful anti-sliding structure.The results of the research provide the idea of h pile with technical reference.
