In this report, the applicability of the proposed method is verified by simulation analysis of in-situ horizontal loading test results of piles with measured shear wave velocity. In addition, a sensitivity analysis of the parameters used for ground spring evaluation was conducted. As a result, it was confirmed that the proposed method can reproduce the horizontal loading test results well. It was also confirmed that the ground spring and the deformation coefficient of the ground were more influential when the pile diameter was large, and the plastic horizontal ground reaction force was more influential when the pile diameter was small.
