This contribution discusses the application of the Random Field theory to geotechnical variables for making prediction on the ultimate bearing capacity and the final settlement of a single pile of 1 m diameter and 24 m length through a piezocone penetration test CPTu drilled into sandy soils at Araquari site (Brazil). From this study the calculated ratio between the measured and the predicted bearing capacity is about two. The distribution of the load along the pile shaft is similar to the measured one although the absolute value of the calculated load is about the half. Thus, in the case of the Araquari sand and silt mixture the characteristic value approach performed by the evaluation of the mean trend and the spatial variability structure of the residuals is highly conservative.

Abstract

This contribution discusses the application of the Random Field theory to geotechnical variables for making prediction on the ultimate bearing capacity and the final settlement of a single pile of 1 m diameter and 24 m length through a piezocone penetration test CPTu drilled into sandy soils at Araquari site (Brazil). From this study the calculated ratio between the measured and the predicted bearing capacity is about two. The distribution of the load along the pile shaft is similar to the measured one although the absolute value of the calculated load is about the half. Thus, in the case of the Araquari sand and silt mixture the characteristic value approach performed by the evaluation of the mean trend and the spatial variability structure of the residuals is highly conservative.
