    Large-scale direct shear tests were conducted in order to evaluate both the shear strength of soil itself and the interface shear strength between soil and geotextile. One type of woven geotextile was used in the experimental program with two types of soil, sand and clay. Total nine tests were conducted in this study. It has been found from the experimental results that the friction angles of sand itself were 31˚ under the unit weights of sand being 1.4 t/㎥. Interface friction angle between woven geotextile and sand showed 26˚ indicating an efficiency of 82%. Similarly, interface friction angle between woven geotextile and clay showed 4.65˚ with the cohesion of 0.08 ㎏/㎠.
