Abstract

In this study, the pullout tests are conducted to evaluate the pullout resistance of the geosynthetic strip with or without bearing resistance zone. The test results are indicated that the pullout resistance of the geosynthetic strip without bearing resistance zone is not affected by horizontal spacing. However, the horizontal spacing of reinforcement with bearing resistance zone affects the bearing resistance. In other words, it is indicated that the bearing resistance at spacing of 210mm is larger than that at spacing of 260mm. This means that the pullout strength at spacing of 210mm is larger than that at spacing of 260mm. Therefore.
