Abstract:

Using the nonlinear finite element method, the influence of parallel and quincuncial layout styles on soil arching effect of double-row anti-slide piles has been studied. It is found that soil arching effect can occur at both the anterior pile and the posterior pile. The soil arching effect of anterior piles and posterior piles can occur easily and distinctly with the quincuncial layout style. It can also be found that the loading at anterior piles is remarkably heavier than that at posterior piles, which suggests that a more economic and reasonable design can be proposed for reducing the design strength of posterior piles.

Key words: anti-slide pile, pile spacing, layout style, soil arching effect
