Axial Response Analysis of Piles in Vertically and Horizontally Non-Homogeneous Soils

摘要

The paper presents a modified procedure for the analysis of the axial response of piles embedded in multi-layered soils. The results obtained by this procedure are compared with those computed by some previous methods and with a limited number of field test measurements. In the determination of the group settlement interaction between piles embedded in multi-layered soils, an additional simple soil mass stiffness model is developed in order to include the horizontal non-homogeneity of the soil due to soil disturbance cause by pile installation. The predictions by this model agree more closely with the observed field test group performance than do predictions by the conventional method which assumes lateral homogeneity of the soil.
