Abstract
Dredged soft clay from the sea-bed of the port of Kobe was employed in on-going project of land reclamation work in North-West part of Kobe airport island. Since the clay was characterized with its super-high water content, a series of geo-grid sheet was displayed on the soft clay ground in order to achieve the prescribed trafficability for vehicles in use for spreading surface soil. Prior to the reclamation work, a trial test was carried out in order to observe the behavior of fully-instrumented geogrid sheet . In addition, the in-soil pull-out test of geogrid was performed for a better understanding into the sheet behavior when subjected to tension force. In this paper, the results of the trial test are discussed based on these in-situ laboratory tests.
