Abstract: 

This study presents the numerical analysis of triaxial drained test results on fine sand specimens reinforced with carpet strips, using the Plaxis software, Two sets of test results of plain coarse and fine sand specimens were also analyzed. This comparative study revealed the following conclusions:
1) The stress-strain and volume change characteristics of plain sand specimens obtained from the laboratory tests and the numerical analyses were agreeable. The accuracy however seems to be controlled by the magnitude of confining pressure and also the size of sand particles. The numerical results of the coarse sand were much more reasonable and comparable.
2) The results for the fine reinforced sand were not quite well and agreeable with the experimental values. The discrepancy was more pronounced for the volume change results, and also with the increase of fiber content or aspect ratio. It seems that the hardening soil model may not be appropriate in capturing the real behavior of fiber reinforced sand particularly with respect to the volume change characteristics.
