Abstract

A three-dimensional nonlinear elastic constitutive model for the original ground and a multi-scale analysis method for partially improved ground have been developed. These were then evaluated by comparing the experimental results of static load-settlement experiments under centrifugal acceleration with results of single and multi-scale numerical analyses. The surface settlements calculated by the proposed model and analysis method are in good agreement with the experimental results and indicate that the resulting surface settlement is uniform over the load-surface area on non-improved sandy ground and nonuniform (greater at the center) on improved sandy ground.
