Reinforced geosynthetic retaining structures are engineering structures that, with the development of technology, have more and more areas of application and characteristics. These are often preferred today, especially as they eliminate architectural concerns with evolving façade element preferences.
Although geosynthetic reinforced walls are similar in design to reinforced concrete retaining walls, the basic elements that make up their structures are different. With the help of a reinforcing element (TechGrid, Enkagrid Pro) used in a suitable filling material used as soil, retaining structures can be formed with the desired height and design features. In a reinforced concrete retaining wall, the element that meets the pressure is concrete, the element that meets tensile stresses is steel reinforcement, and the element that meets the pressure in geosynthetic-reinforced walls is the backfill material and the element that meets the tensile stress requirements - this is the reinforcement used (TechGrid, Enkagrid Pro). Thus, restraining structures with the same behavior characteristics differ in their structural elements.
When investigating the behavior of engineering structures built in recent years in conditions of earthquakes, reinforced geosynthetic materials for walls are often preferred due to their flexibility and elasticity in conditions of earthquakes, especially at heights above a certain average value (more than 5 m). Due to their flexible behavior, they have been actively used in the mining and industrial areas, especially in the recent period, as they do not show the problems with collapse, cracking and massive collapse characteristic of reinforced concrete walls, which are their counterparts, due to their properties. performance in areas with high acceleration of earthquakes.
Geosynthetic Reinforced Wall structures can be designed according to BS8006: 2010, Asshto (FHWA), Eurocode 7/8, or they can be designed without standards. The criteria taken into account in their design are external and internal stability checks. The reinforcement elements used (TechGrid, Enkagrid Pro) are determined according to internal stability studies; The type of reinforcement should be preferred depending on the composition of the backfill material used.
Wall types depending on the facing element used:
- Block wall
- Green wall
- Uniting wall
- Earthen concrete wall
Sectors with geosynthetic reinforced walls:
- Mine sites (crushing wall, crushing wall, unit support structure, service roads, etc.)
- Industrial sites
- Airport territory
- Housing projects
- Railways
- Solid waste landfills
- Dehydration of fields
- Pond fields
