Geosynthetic-reinforced soil retaining walls subjected to surcharge loads
Currently there are many solutions to improve soil properties. Geosynthetic materials (geogrids and geotextiles) are particularly useful in reinforced soil systems. Geosynthetic-reinforced structures have been widely used in road engineering and in the construction of railways due to their economy and effectiveness compared to the traditional soil improvement methods. A considerable number of retaining structures have been successfully constructed using geosynthetic reinforcement layers. In many of these retaining structures, footings are located on the backfill and over the soil (e.g. footings on bridge abutments or roads located on top of the retaining structure). Despite the increasing use of geosynthetic-reinforced soil systems for retaining structures, still uncertainty exists concerning the real interaction of these materials with the soil and consequently, the current design methods need validation for different conditions and interactions. The soil-geosynthetic interaction can be very complex because it is affected by structural, geometrical, and mechanical characteristics of the geosynthetic, by the mechanical properties of the soil and by boundaries and loading conditions. This thesis starts with exploring the existing literatures on the soil-geosynthetic interactions in MSE walls. The review of the literatures underpins further development in the soil-geosynthetic interaction by experimental, analytical and numerical modelling for the mechanically stabilized earth wall systems and under the strip footing load. In mechanically stabilized earth walls and especially under the strip footing load, the necessary reinforcement length and consequently the size of the reinforced block depend on the reinforcement layers stiffness and strength, soil properties and interface apparent coefficient of friction. Next, model test results obtained from full-scale tests on the geogrid reinforced stabilized earth walls were analysed with analytical methods. The model MSE walls were prepared and tested at Brandenburg ...
