Prediction and management of consolidation settlement with master-curve method in Tokyo International Airport

摘要

A method using master curves was used in the management of consolidation settlement in the third-phase area of the Tokyo International Airport Offshore Expansion Project. In the prediction of consolidation settlement of grounds, a predicting method capable of simulating the actual settlement with high accuracy is indispensable. On the other hand, required in quick ground-improvement work is a system which enables simplified prediction and quick feedback of predicted results to the construction works. The mastercurve method proposed in this paper is a settlement-predicting method which uses simplified models and field data to make prediction of the same accuracy level as numerically analyzing methods.
