STUDY ON THE INTERACTIVE EFFECT BETWEEN GEOGRID AND WEATHERED MUDSTONE

The interactive behavior between the geogrid and the soil mass is one of the major factors determining the viability of the reinforced structure. This study performed a number of pullout tests on geogrids of different specimen and aperture size to simulate the pullout failure mechanism of the geogrid under different conditions. The results indicate that specimen size affects the pullout resistance and the tensile force-displacement behaviors. Moreover, no matter if the spacing between or the length of the transverse ribs were modified, altering the aperture of the geogrid had a significant effect on pullout test results. Generally, pullout resistance development can be categorized in the following three stages: (1) the period of frictional resistance development, (2) the period of passive resistance development, and (3) the period of soil mass plasticity.
