An apparatus measures a supporting force of ferroconcrete piles by means of a bi-directional front end oil pressure loading apparatus using a high pressure loading system capable of measuring a supporting force, a sinking amount and an axis load distribution on the ferroconcrete piles. The apparatus comprises: a steel plate having a predetermined thickness and diameter and including upper and lower discs having penetration holes through which concrete passes; a fixing member for separating the discs from each other by a predetermined distance; a high oil pressure cylinder for producing an oil pressure force; an oil cylinder inflation displacement measuring sensor for measuring a displacement; an upper displacement measuring rod coupled to the upper disc for measuring a displacement of the upper disc; a lower displacement measuring rod coupled to the upper disc for measuring a displacement of the lower disc; an axis load transition measuring instrument including a tremie induction tube coupled to the upper disc for guiding concrete to the penetration holes; iron elements coupled to the upper disc; a load sensor for measuring ground abrasion; and a sensor line for transferring a signal and current to the load sensor. A corresponding method is disclosed.
