PROBLEM TO BE SOLVED: To provide a design method of a pile foundation capable of surely attaining a required pile tip bearing force while further accurately evaluating the pile tip bearing force.SOLUTION: A design method of a pile foundation comprises a characteristic data preparation process, a tip bearing force factor acquisition process, a peripheral surface frictional resistance contribution quantity arithmetic operation process, a vertical directional resistance contribution quantity arithmetic operation process and a parameter determination process. In the vertical directional resistance contribution quantity arithmetic operation process, a contribution quantity of vertical directional resistance of a lower end surface of one foot protection part included in a tip bearing force factor, is determined based on the tip bearing force factor of one pile foundation determined by the tip bearing force factor acquisition process and a contribution quantity of peripheral surface frictional resistance of one foot protection part determined by the peripheral surface frictional resistance contribution quantity arithmetic operation process. In the parameter determination process, a diameter of a precast pile of a target capable of constituting a pile foundation having the tip bearing force factor of the target and the length of a part of the foot protection part of the target deeper than the lower end of the precast pile of the target, are determined based on the contribution quantity of the vertical directional resistance determined by the vertical directional resistance contribution quantity arithmetic operation process.SELECTED DRAWING: Figure 3
