Abstract
In renovation work for the purpose of improving water shielding properties of an aging embankment of irrigation pond, a method for installing a bentonite geosynthetic clay liner may be adopted. In this case, it is important to have a precise understanding of the frictional interaction properties between geosynthetic clay liner and soil in the embankment for the investigation of stability of the embankment against earthquakes and heavy rainfall after renovation. For this reason, in this study, direct box shear test apparatus was used to fully examine the frictional interaction properties between the bentonite geosynthetic clay liner and the soil used in the pond embankment under low stress, the deformation characteristics of bentonite within the liner, etc.
