PROBLEM TO BE SOLVED: To provide a vertical loading test method of a prefabricated pile capable of revaluating a proper supporting function by measuring the front end bearing capacity of the prefabricated pile in a place deeper than the groundwater level and the circumferential frictional force in an existing state or in a reusable state. SOLUTION: An edge cut between a pile head and a foundation member is made at the outer circumferential position of a pile head of the prefabricated pile in the foundation member swallowing the pile head of the prefabricated pile aiming at a test or a near position separated from the outer circumferential position of the pile head by leaving a part of the lower end section of the foundation member, a recess or a cut end formed by the edge cut is shielded by a joint member equipped with flexibility or expansion and contraction nature and cut-off efficiency in a water-tightness to perform water cutoff, a loading test device is assembled to the upper end of the prefabricated pile, a vertical load is added to the prefabricated pile, and first of all, the remaining section of the foundation member is fractured to measure the supporting performance of the prefabricated pile.
