Extremely soft clay ground formed by dredging is located in North-West part of Kobe Airport Island. In an attempt to make the ground for land use in near future, soil spreading work using geogrid sheet was employed in order to acieve the prescribed trafficability of the spreading machine. Prior to the work, a trial work using fully instrumented geogrid sheet was carried out in order to examine the details of the construction scheme work. In this paper, the results of two-dimentional FE simulation considering soil-geogrid interaction are presented. In this analysis, an interface element reflecting properly the result of in-soil pull-out test of the geogrid was employed. Ground behavior of extremely soft clay ground in the event of soil spreading with geogrid sheet was successfully evaluated by 2D FE analysis.
