ANALYSIS OF PILE SPACING BETWEEN ANTI-SLODING PILES AND PETAINING PILES IN ACCORDANCE WITH SOIL ARCHING EFFECT

Anti-sliding pile are used to stabilize slopes and to control landslide for a long history. It is because of the soil arching effect between the piles that can work effectively. According to the limit equilibrium of the soil mass,the horizontal soil arching effect between the cylindrical anti-sliding piles in the earth is studied and the formula for largest spacing between the piles is proposed. Then, through a case study, the physical meanings and the feasibility of the largest spacing between the piles are discussed. Then the suitable spacing between the piles is proposed in consideration of the soil arching effect. Finally, Some useful suggestions for the slope engineering designing are also proposed in the paper.
