In the stability analysis of the slope with stabilizing piles, the location of the sliding surface is usually determined in advance by field investigations. In this paper, the design method for piles in a row within a slope of such a fixed sliding surface as in landslide has been investigated. That is, studies on the effect of many factors of pile on the slope-stability are carried out for an example of a landslide slope containing stabilizing piles and a new design method is proposed for the stabilizing piles against landslide.The results show that such factors as the interval between piles, the fixity condition of pile head, the pile length above sliding surface, the pile diameter and the stiffness of steel pipe pile have considerable effect on the slope-stability. In the proposed design method, such five factors can be decided systematically. Furthermore, an example of design is shown, in which important factors in pile design are brought out and illustrated.
