In this paper, theoretical analysis method for free-headed long piles and free-heade arbitrary length piles is derived as follows : H_u, V_u・・=f(ω, θ_0, B, E, H_0, M_y, φ, C, δ, C_p, δ_r, γ, q) where H_u : horizontal component of ultimate load V_u : horizontal component of ultimate load ω : angle of load on a pile θ_0 : angle of a pile B : diameter or width of a pile E : distance from the ground surface of a pile to the pile head H_0 : pile length in the ground M_y : yield moment of a pile φ: angle of internal friction of soil C : cohesion of soil δ:angle of friction between pile surface and soil C_p : cohesion between pile surface and soil δ_r : angle of friction between tip of pile and soil γ : unit weight of soil q : distributed loads working on ground surface The important feature of this method is as follows : It is possible to solve the problems of vertical piles and batter piles subjected to inclined loads, and the problems of the ground containing both cohesion C and the angle of internal friction φ.
