Abstract
To evaluate the permeability of the ground reinforced with Geogrid, two types of tests; a triaxial permeability test and a large scale-pit test were conducted. The former is an element test which is not allowed to move soil particles under different conditions. The latter is a model test which is not allowed to move soil particles under different conditions. The results of the former test concluded that there is no difference between specimen reinforced with Geogrid and specimen unreinforced Geogrid when their compaction degrees were enough. The results of the latter test concluded that Geogrid restricts the movement of soil particles.
