Zusammenfassung:To provide a pile performance estimation method that can estimate a static spring representing a pile performance at low cost.SOLUTION: A performance estimation method of a pile 10 applies an impact force of more than 0 kN and 20 kN or less from the vertical or horizontal direction to a pile head 12 of the pile 10 buried in a ground, and estimates the static spring of the pile 10 based on the impact force with respect to the displacement of the pile head 12 from vibration data of the pile head 12 due to the impact force.SELECTED DRAWING: Figure 1 【課題】低コストでありながら、杭の性能を表す静的ばねを推定することができる杭の性能推定方法を提供する。【解決手段】杭１０の性能推定方法は、地中に埋設された杭１０の杭頭１２に対し鉛直方向または水平方向から０ｋＮを超え２０ｋＮ以下の衝撃力を加え、衝撃力による杭頭１２の振動データから杭頭１２の変位に対する衝撃力に基づいて杭１０の静的ばねを推定する。【選択図】図１
