    Abstract

    Bearing capacity of the ground improved by sand compaction pile method is investigated primarily by a series of centrifuge model tests. Bearing capacities obtained under the various loading conditions are well explained by the simple stability analysis which has been commonly employed in Japan. The effectiveness of a simple construction control diagram is confirmed based on the deformation of the ground. These findings are also verified by the full scale load test leading to failure of the improved ground.
