This study proposed an ultimate lateral resistance calculation equation for array piles on which lateral loads act using a strain wedge model. The resistance properties were divided into the lateral resistance of earth pressure on a wedge back, shearing resistance on a wedge side, and friction resistance between the pile and the soil. The value of their resultant forces subtracting overlap resistance was expressed as the ultimate lateral resistance of an array pile. This study compared and analyzed the existing research results to verify the validity of the proposed equation. The results showed that the proposed equation was larger at the front-row pile, approximate at the middle-row pile, and smaller at the back-row pile, but the total ultimate lateral resistance turned out to be similar.
