WALLS IN REINFORCED SOIL
Simple geometry and reinforcement, walls in soil reinforced with geogrids or geotextiles
The reinforced soil walls are gravity retaining structures, composed by the inclusion to the soil mass of different reinforcement elements such as geotextiles or geogrids which provide important advantages to their mechanical resistance and deformations. The multiple applications of these structures make it necessary to characterize and evaluate the different geometries that allow their flexibility. The two main groups are: simple geometries and complex geometries.
TIP : Simple geometry walls are characterized by a simple configuration on a single façade, which has an inclination between 70° and 90°.
In the graph above we can identify the different components of a reinforced soil wall, fundamental for design and adequate long-term performance.
GEOGRIDS OR GEOTEXTILES AS A REINFORCEMENT ELEMENT IN WALLS
Both geotextiles and geogrids can be incorporated as reinforcement elements of a reinforced soil wall, both of which provide the required contribution to the stability and containment conditions of the structure.
Geosynthetic formed by a regular network of elements integrally connected with openings that allow the entanglement with the surrounding soil, rock, earth and other materials to provide them with reinforcement
It is a geotextile woven with fibers of the exclusive G5 Multifilament of high tenacity polyester (PET), characterized by high mechanical and hydraulic performance. Its structure is defined by the weft insertion technique, which gives it the fastest response in tension to soil deformations and stability in the performance. hydraulic at any level of stress or confinement.
It is ideal for the reinforcement of subgrade soils and granular layers in pavements, embankments and retaining structures in reinforced soil.
TIP : The walls reinforced with geotextiles require a coating on the facade to guarantee their aesthetics in the long term.
