Anti-sliding pile is one of earth structures

which is commonly used in the slope engineering. Anti-sliding piles can quickly and safely constructed and become one of the main measures of slope stabilization. In designing anti-sliding piles the space between piles is one of the most important parameters to be considered. In conventional design of anti-sliding piles

this parameter is empirically estimated

usually on over-conservative side. Considering the soil arching effect

the pile space could be larger than usual and less piles would be required for slope stabilization. The mechanism

characteristics and influencing factors of soil arching effect are studied in this paper

and a procedure is proposed for computing the pile space considering the soil arching effect. A case study is given of computation of the pile space considering soil arching effect using Matlab software.
