Abstract: This paper presents the PLAXIS numerical analysis results of htype piles used for landslide mitigation in Ningde area. 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.

Key words: slope stability, h-type piles for landslide mitigation, double row pile frames, finite element analysis
