Abstract: In this paper, we investigated how to utilize the
small-strain stiffness in order to estimate the settlement of shallow
foundations on granular soils. For this purpose, a power law equation between
normalized shear modulus and shear strain was presented. Based on theory of
elasticity and proposed equation, a new method in term of small-strain
stiffness was suggested to estimate the immediate settlement. In order to
evaluate the proposed method, a series of case history included plate and
footing loading tests and seismic geophysical tests was studied. These field
measurements are compared to the predicted values. The result indicated that
the proposed method in this study can be effectively used to predict the
settlement of footing on granular soils and that were more accurate than the
SPT or CPT based predictions.
