Abstract
A simplified methodology is proposed for the stability analysis of slopes reinforced with one row of piles. To account for the presence of piles, an existing method which is based on the theory of plasticity is used to determine the lateral forces acting on the piles. Then, the kinematic approach of limit analysis is used to analyze the stability of the slope. The rate of external work due to the pile force is added to the energy equation and expressions are derived to calculate the safety factor of slope reinforced with piles. Using the proposed method, a study is carried out to illustrate the effect of piles on slope stability. Finally, the most suitable location of piles within the slope and the effect of pile spacing and diameter on the safety factor are discussed.
