| Anti-slide piles are vertical members from reinforced concrete used to resist the landslide and improve the slope stability. Recently, the anti-slide piles are widely used because it's characterized by high slide resistance, good retaining effect, small masonry compared with the anti-slide retaining wall. The goal of this paper is studying the parameters effect on the factors of safety for slopes and the performance of the pile-stabilized slopes. These factors include the pile diameter, pile spacing, the length of the pile embedded in the stable zone (under slip surface), and the most suitable location of the piles within the slope. The finite element program GEO5 was used in this analysis to study the stability of slopes using the anti-slide pile. The results of the finite element program indicated that using the anti-slide piles is an effective method to increase the factor of safety for the slopes. As the piles spacing increase, the factor of safety decreases. The optimum pile spacing occurred when S= D. The critical embedded length of pile occurs when the depth of the unstable zone above the slip surface is equal to the embedded length of piles. The optimum position of the piles is in the middle of the slope. | ||||
