Abstract
In order to validate the three-dimensional nonlinear elastic constitutive model for the original ground and the multiscale analysis method for partially improved grounds, both of which have been developed by the authors in the previous report, we compare the results of the static load-settlement experiments under centrifuge gravity and those of singlescale and multi-scale numerical analyses. The surface settlements calculated by the proposed model and analysis method are in good agreement with the experimental results that show that the resulting surface settlement is uniform in load-surface area on non-improved sandy ground and non-uniform (larger on center position) on improved sandy ground. To verify the practical applicability of the method, we also apply it to the in-situ load-settlement problem whose site is partially piled with 250 piles. The analysis results agree with the in-situ measured data.
