  • To explore a better anti-sliding structure between h-type anti-slide piles and cantilevered double-row anti-slide piles, the finite element software MIDAS/GTS was used and the three-dimensional finite element analysis models for h-type anti-slide piles and cantilevered double-row anti-slide piles were constructed. Then, the displacement, internal force of piles and slope support effect of the two anti-slide pile structures were compared and analyzed. The results showed that: 1) There were significant differences between the two types of anti-slide pile systems in terms of displacement and internal force of piles. Compared with cantilevered double-row anti-slide piles, h-type anti-slide piles were better to coordinate flexural moment and shear force of the front and rear piles, as well as displacement of piles. 2) Compared with cantilevered double-row anti-slide piles, the support effect of h-type anti-slide piles was more significant. The safety factor of slope stability increased by 21.8%, simultaneously, the maximum shear strain decreased by 63.6%. 3) Compared with the cantilevered double-row anti-slide piles, the theoretical calculations on internal force of the front and rear piles in the h-type anti-slide pile systems were more reasonable. It also showed the advantage of h-type anti-slide piles in coordination of the internal force.
