    Abstract

    The sand compaction pile method (hereinafter abbreviated as SCP method) has been developed in Japan as an improvement method for soft ground. One of the reasons of the above is that SCP method can be applied to both sandy and clayey soil. Complicated soil strata in Japan have also contributed to the development of this method. This paper evaluates and verifies the applicability of the design procedure of SCP method to sandy and clayey grounds by comparing the measured data with designed values. Moreover the latest technolgy of SCP method, that is the Mechatronic Consolidation System which can set up sand compaction piles in accordance with the variation of soil properties, is also introduced.
