Suction caissons are of the best methods for implementing structures, especiallyfor offshorewind turbines in deep waters. Such piles are usually applied for restraining stress and tension of offshore structures. For complexity of such piles plan, it can be referred to determining their tension capacity. This study seeks to analyze the plan, to analyze and validate other related researches and also tries toachieve tension capacity of the pile affected by vertical load and its amount of

... nt with the change inbasic parameters of soil like: soil adhesion and its angle of friction using Plaxis 2DFinite Element software. Results show that under mentioned forces, increasing in soil adhesion causes decrease in lateral displacement of the pile. Increasing in angle of friction also makes decrease in lateral displacement of the pile, but the effect of soil angle of friction on lateral displacement of the pile is more than soil adhesion on this parameter. The higher the ratio pile length to its diameter, the higher is the lateral displacement of the pile.
