To obtain data having high reliability required for determining bearing capacity of the pile in a short time and economically, a pseudostatic pile load testing method comprises processes that a drop height of a heavy weight ( 2 ) dropped on a pile head of a pile ( 1 ) is changed higher step by step, the heavy weight ( 2 ) is dropped from each of the heights, a time change of an acceleration of the pile head by that impact is determined by an accelerometer ( 4 ) installed at the pile head, and a displacement of the pile head is determined as an integrated value of the acceleration determined by the accelerometer ( 4 ).
