A measurement method for a granular compaction pile 10 using a crosshole seismic test. The measurement method includes forming first to fifth measurement holes around the granular compaction pile, injecting grouting material into the first to fifth measurement holes and inserting casings into the first to fifth measurement holes, respectively, and installing an oscillator and a detector of a crosshole seismic tester in the first to fifth holes and detecting a velocity of a shearing wave, thereby measuring a diameter of the granular compaction pile according to a construction depth thereof. The shape and the diameter of the granular compaction pile are easily checked without causing damage to the granular compaction pile.
