| Abstract: | Based on a built cub-geogrids-reinforced earth retaining wall and self-consistent theory,a mechanical model for soil-reinforcement composite material is built up,with which,the performance of the cubgeogrids-reinforced earth retaining wall is analyzed.The model for calculating the cub-geogrides-reinforced earth wall is presented after analysis,baed on which,the failure model is analyzed.It is concluded that the cubgeogrides-reinforced wall has a good mechanical property and it can weet the demands of the ci... |
