| Abstract: | The simulation model is established by solid mass element and geogrids which are based on FLAC3D.The rock and mortar is simulated by the unit grid and the geogrids are simulated by structural elements,thus a series of computational experiments for the different layers location and interval are performed.After that,the performance of reinforced embankment is analysed.what’s more,the mechanism and preferment method in reinforcement embankment are deeply discussed. |
