The aim of this paper is to investigate the pile end bearing capacity in highly breakable sands such as carbonate sand and decomposed granite soil, comparing with that in the hard grained silica sands, based on a series of triaxial compression and model pile tests, and further to discuss the estimating method of pile end bearing capacity in sands, considering the material compressibility. As a result, it was found that, even if much higher internal friction angle was obtained, the low pile end bearing capacity could be observed in the case of highly compressible sands. Further, a conventional manner to predict the end bearing capacity was presented empirically, combining the compressibility to Prandtl's bearing factor for general shear failure.
