ASSESSMENT OF HYBRID MODEL FOR PILE GROUPS

The effects of mathematical modeling of pile groups by representing the soil response against the piles through unit-soil-resistance relationships for isolated piles and using elasticity methods to account for group effects were studied by modeling three pile-group tests in clay reported in the literature. Emphasis is placed on the effect of varying the Young's modulus of the soil surrounding the piles and the effects of imperfect pile alignment. The errors in computed cap translation were small; and the errors in load distribution to piles and the axial load distribution along the piles were insignificantly affected by the value of the modulus and could not be eliminated by this modeling method.
