An estimating method of lateral load acting on stabilizing piles in a raw due to the plastic deformation of soil for landslide was discussed in this paper. Special emphasis was put on the problems of the space between stabilizing piles and of lateral load induced in piles through the surrounding soils due to plastic deformation in the vicinity of piles. In order to obtain an analytical result of the lateral load acting on stabilizing piles, the authors tried to solve the equilibrium equation of the lateral forses in the small element of the surrounding soil of piles. The equation based on some assumptions such as the Mohr-Coulomb's yield criterion of soil and the non-deformability of stabilizing piles. Particularly, the influence of shearing stress induced by the friction between soil and piles and the normal stress on the failure surface as the plastic yield condition were taken into consideration in the analysis.
