Abstract

In this paper, we investigated how to utilize the small-strain stiffness order to estimate the settlement of shallow foundation on granular soils. For this purpose, a power law equation between normalized shear modulus and shear strain was presented. Based on elasticity theory and proposed equation, a new method in term of small-strain stiffness was suggested order to estimate the immediate settlement. In order to evaluate the proposed method, a series case history was studied, that included the loading tests and seismic geophysical tests. 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.

A Non-Linear Method to Estimate Elastic Settlement of Shallow Foundations Using Small-Strain Stiffness

Chicago, Illinois

In this paper, we investigated how to utilize the small-strain stiffness order to estimate the settlement of shallow foundation on granular soils. For this purpose, a power law equation between normalized shear modulus and shear strain was presented. Based on elasticity theory and proposed equation, a new method in term of small-strain stiffness was suggested order to estimate the immediate settlement. In order to evaluate the proposed method, a series case history was studied, that included the loading tests and seismic geophysical tests. 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.
