A method of analysis for the pile-cap-pile-group interaction problem in nonhomogeneous soil is described. The results of a parametric study are described to illustrate the influence of the various factors on the behavior of this pile-group system. Case studies of field tests on pile groups in clay with ground-contacting caps are also presented. In most of the cases analyzed in the study the use of an equivalent homogeneous-soil profile tends to underestimate the stiffness of the groups. The effect of a cap does not increase the stiffness of the group significantly and this effect is even less significant in the nonhomogeneous-soil profiles. Other study findings are also discussed.
