For the design of pile foundation under vertical load, the amount of the settlement is important as well as the bearing capacity. So it is necessary for the establishment of the method to calculate the settlement exactly. The technique to estimate the load-settlement relations is examined in this paper based on many vertical loading tests of preboring nodular piles. For the calculation of load-settlement relations, the load transfer analysis is applied with the frictional resistance and point resistance in unit area by digging diameter estimated from N-value of the ground. The results of estimation by proposed method are closed to the measured values.
