| Abstract: | This paper analyzed the harm of rock embankment and proposed using geosynthetic materials treating stone-filled embankment. By using plane finite element method,the reinforcing effect of geo- synthetic materials for rock embankment under the action of traffic load and self-weight is analyzed. The stress distribution and displacement change in rock embankment are compared between those paved and un-paved with geosynthetic materials. Based on this, the theoretical calculation model is suggested for stress analysis of geosynthetic materials treating rock embarkment and separating coarse and fine filling. |
