| This research performed the laboratory model tests for Top-Base Foundation developed in Japan and Floating Top-Base Foundation developed in Korea on the typical clayey soft soils, namely, clay, clayey silt and clayey sand. The performances of the two types of top-base foundation were compared with each other and evaluated by measuring load-settlement, heaving of foundation side, ground stress distribution in this model tests. The change of settlement caused by the increase of top base width was also analyzed. As a result of the model tests, Floating Top-Base Foundation showed better performance in bearing capacity improvement, settlement decrease, stress dispersion effect and lateral confinement force. And settlement caused by the increase of top base width converged to a regular value from $5{ imes}5$ layout of the width. |
