A simple and rational method for evaluating the end bearing capacity and the tip settlement of pile driven in sandy ground has been developed on the basis of the theoretical and experimental considerations. This method assumes a failure mode with spherical cavity expansion pressure, taking account of the compressibility of soil. The effects of the compressibility, and shear stiffness of sand friction angle on the pile end-bearing capacity are discussed, together with the practical determination procedure of the experimental parameters needed in the model related to the information of soil data. The applicability of the proposed method is verified in comparison with the results of model tests as well as in situ pile loading tests on sandy grounds.
