A basic method for stability analysis of the slope containing piles in a row is described, using the theoretical equation of lateral force acting on piles in a row due to plastically deforming ground, which has already been derived by the authors. Studies of the effect of many factors on pile and slope on the slope-stability are carried out for an example of the foundation piles of landing pier in a harbor and a design method is proposed for the stability analysis of the slope with landing pier.The results show that such factors as the position of pile's row, the fixity condition of the pile head, the interval between piles, the pile diameter, the thickness of the pipe pile and the slope gradient have much effect on the slope-stability. In the proposed design method, such six factors can be considered systematically. Moreover, an example is shown, in which important factors in pile design are brought out and illustrated.
