Horizontal Deformation of Geogrid-reinforced Soil Retaining Wall with Wrapped-around Facing
碩士 === 國立雲林科技大學 === 營建工程系 === 102 === In this study, the re-analyzed test results of facing deformation of a series of model tests on wrap-faced geogrid-reinforced soil (GRS) retaining wall were presented. The adopted backfill of GRS retaining wall was sand or gravel. Four types of geogrids having d...

The adopted backfill of GRS retaining wall was sand or gravel. Four types of geogrids having different nominal strengths were used. For the case of setback distance equal to 50cm, the dimensions of the model wall were 183 cm (width) × 80 cm (depth) × 112 cm (height). A strip footing of 30 cm wide, having its setback distance equal to 35cm, 50cm, or 65cm, was located on the surface of backfill to resist the applied vertical load during model test. The analyzed results indicate that the maximum lateral deformation occurs at the top of facing of unreinforced wall and at central height for reinforced case. Under the same applied footing pressure, the lateral deformation of reinforced wall is smaller than that of unreinforced one. For unreinforced wall, the lateral deformation decreases with an increase in the setback distance of footing; however, the above trend is not significant for reinforced wall. It is found that under otherwise identical conditions the lateral deformation of gravel wall is smaller than that of sand wall both for reinforced and unreinforced cases. To sum up, the lateral deformation of wrap-faced retailing wall is found to be influenced by the stiffness of geogrid, the setback distance and the particle size of backfill.
