LONG-TERM PULL-OUT OF POLYMER GRIDS IN SAND ---PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM ON THEORY AND PRACTICE OF EARTH REINFORCEMENT, FUKUOKA, KYUSHU, JAPAN, 5-7 OCTOBER 1988

In order to establish the rational design methods for geotextile reinforced structures, it is necessary to clarify the long-term friction/adhesion characteristics between soil and geotextiles. Therefore, both the displacement-controlled short-term pull-out tests, and load-controlled long-term pull-out tests were conducted respectively for the polymer grids embedded in sand. From the test results, it was found that, with a constant pull-out force applied to the polymer grid embedded in sand, each bar of the polymer grid is displaced with time, however, its free end is hardly displaced with time at all, and that the increase with time in the deformation of polymer grid in sand is smaller than the increase obtained from the results of tensile tests. For the covering abstract of the symposium see IRRD 818063.
