摘　　要：以宁德地区某一典型边坡支护工程为背景,运用有限元软件PLAXIS分析了h型抗滑桩的受力、变形特性和坡体稳定性,与单排桩和门架式双排桩支护结构进行对比分析。结果表明,主桩的弯矩和剪力均在冠梁连接处出现突变,主桩上桩体在受力性能表现为悬臂梁受力特性,下桩体和副桩共同作用表现为刚架结构受力特性,在变形性能上可以发挥门架式双排桩的特性。即h型抗滑桩兼有单排桩和门架式双排桩支护结构受力特性,同时具有侧向刚度大、侧向位移小的特点。This paper presents the PLAXIS numerical analysis results of h-type piles used for landslide mitigation in Ningde ar- ea. The stress and strain in the piles and the stability of the slope are discussed in the paper. The results of the single row piles and the h-type piles are compared. The results show that the bending moment and the shear force in the front row piles have a sudden change at the horizontal beam location. At the upper portion of h type piles, cantilever beam behavior is observed. A rigid frame performance is measured at the lower portion of this type of structure.
