A method of estimation of in-soil deformation behavior of geogrid, the end of which is fixed to the ground, by using the results obtained from soil-geogrid direct shear test was proposed. From a series of calculation performed by changing the embedment length or the stiffness of geogrid, it was found that the longer the length or the smaller the stiffness of the geogrid, the smaller the influence of the end restraint (free or fixed end) on the in-soil deformation behavior of geogrid. It was also found that the pull-out force versus displacement relationship at small displacement is strongly dependent on the stiffness of geogrid irrespective of the embedment length of geogrid and the condition of end restraint in the ground.
