BEARING CAPACITY OF EXPANDED-BASE PILES IN SAND

The results are presented of tests on 93 expanded-base piles from 73 sites throughout the eastern United States. The results are used to develop empirical correlations between pile-point resistance and standard penetration N-values for both short and long piles in relatively homogeneous soils and where the bearing stratum is overlain by soft, compressible soils. Modifications are proposed to conventional bearing capacity analysis to account for the reduction in the friction angle of the soil with increasing confining pressurue, which results in good agreement between measured and caluclated point resistances.
