On the "Yumeshima" man-made island off the coast of Osaka, large-scale work is currently underway to reinforce very soft clayey ground by covering it with geosynthetics. For this work, method and specification decisions had to be made only after verifying the load-bearing capacity of the reinforced ground and applicability of a conventional design method. Loading tests of very soft clayey soil were conducted to determine the reinforced ground's load-bearing characteristics. Applicability of a load-bearing capacity formula for the geosynthetic reinforcement method to the soft ground and use of a new evaluation method based on finite element analysis were also considered.
