Abstract

Full scale size model tests of the top-base foundation was performed in siwha marine clay and the site measurement results were compared with the analytical results from finite different programs, FLAC-2D to investigate the behavior of top-base foundation. The stress distribution obtained from the numerical analysis for the various types of foundation were compared and analysed during the application of allowable load as well as yield load. It was found that the top-base foundation prevents the lateral deformation of soft ground and stress dispersion effect to reduce the surface settlement, and that the foundation creates uniform stress distribution around it, therefore increasing bearing capacity.
