摘要
In this paper, the comparison o of the two experimental methods is carried out according to the results from direct shear test and pull-out test. It’s discussed that the differences and reasons of the interface shear strength obtained from direct shear test and pull-out test. The results of test show that: for woven geotextiles, the shear strength from direct shear test and pull-out test is more or less the same, but the peak displacement of which is so much different; as for the glass fiber grid, the shear strength of direct shear test is greater than that of pull-out test.
