An Original Testing Apparatus for Rapid Pull-Out Test
Abstract: Pull-out test is
commonly used to investigate the pull-out behavior of geotextile reinforcement
embedded in soil. It is also used by different authors to propose interface
friction angles values. Unfortunately these works mainly deal with cyclic
loadings with reference to seismic action, which are believed to be different
to the load exposed to reinforced earthworks due to lateral impacts. Therefore
an original rapid pull-out test apparatus is proposed in this study. This
article assess the proposed test method in addressing the rapid pull-out
response of a geotextile embedded in soil. The testing apparatus allows
investigating shear velocities within the range of 0.1 to 1.2 m/s. This test
method seems promising in addressing the response of soil-geotextile interfaces
under dynamic loadings. Nevertheless, improvements concerning the testing
apparatus are still required. The loading system could be modified to avoid
oscillations and specific equipment should be added to increase the normal
stress.
