Abstract
In order to construct a geogrid reinforced embankment on soft ground, it is significant to forecast its deformation in terms of the function as well as to evaluate safety factor. For that purpose, pull-out resistance of an embedded geogrid must be grasped. Even if various geogrids have the same tensile strength, they seem to display the different reinforcement force depending on their geometrical forms and surface states. In this paper, firstly the interaction between soil and a geogrid which affects pull-out resistance was examined based on pull-out test results. Secondly, influence of the material properties on the stability of an embankment on soft ground was analyzed from two aspects of reinforcement force and embankment deformation. As a result, the importance of the material properties for the stability evaluation was shown.
