  • In order to investigate the effect of aperture shape on the geogrid-soil interface behavior, tensile tests were conducted using two kinds of geogrids with triangular apertures and rectangular apertures, which are of similar aperture size and mechanical properties. The effect of aperture shape on the geogrid-soil interface behavior under different normal pressures and pullout test directions were analyzed in terms of the pullout resistance, shear strength of geogrid-soil interface, apparent friction coefficient and geogrid rib deformation. The results show that the geogrid with triangular apertures plays a better role than the geogrid with rectangular apertures in restraining the lateral displacement of soil. For the geogrid with triangular apertures, the peak values of friction angle in cases TX_0 and TX_90 were 48.2 and 38.2, respectively, while the peak value of friction angle in case SS20 case was only 35.9. The flexural deformation of different degrees was observed in the horizontal and diagonal ribs of the geogrid with triangular apertures during the pullout test, while the ribs of the geogrid with rectangular apertures mainly presented a tensile deformation.
