Abstract
A comparison of strength characteristics of two types of geotextile subjected to pullout force was made by means of in-situ pullout test. It was well demonstrated that the pullout strength property consisted of two components; i.e., the frictional resistance between soil and geotextile, together with in-soil interlocking effect of geotextile. Moreover, an integral type at the lattice nodal point exhibited larger interlocking effect than an bonded type. Based on the test results, it is strongly suggested to employ an integral type of geotextile in well-compacted fill material so that the pullout deformation of geotextile may well be restrained due to the interlocking effect.
