ADVANTAGES OF GEOGRIDS REINFORCED SOIL WALLS IN HIGH SEISMIC RISK ZONES
Seismic risk refers to the probability and consequences of earthquakes occurring in a given geographic area, affecting both infrastructure and human lives. This risk is assessed by considering the historical seismic activity, the geology of the site and the vulnerability of the buildings in the area.

Given this condition, it is essential to build durable and resistant containment works. These structures, designed to withstand the forces and movements generated by earthquakes, not only protect people and property, but also minimize damage and ensure the continuity of economic and social activities. The implementation of earthquake-resistant construction standards and the use of advanced materials and techniques are essential to ensure the safety and resilience of communities in these areas.
Although concrete retaining walls are robust structures, under the action of an earthquake they can suffer structural failures such as cracks, fractures and eventually sectioning, which causes them to lose their functional condition and become potential risks for nearby communities. seismic resistance of soil walls reinforced with geogrids
One of the major advantages of MSE walls is their flexibility and ability to tolerate deformations. Based on observations in seismically active zones, these structures have demonstrated greater resistance to seismic loading than rigid concrete wall structures, basically because they do not impose a change of stiffness on the ground when the seismic wave passes through. This behavior is associated with the following characteristics of this technology:
Controlled deformations: Thanks to the flexibility and ductility of the reinforcements, these walls can undergo deformations without collapsing, allowing stress redistribution and absorption of seismic energy.
Adaptability to future seismic loads: Reinforced soil walls can be designed and adapted to improve their performance in future earthquakes by incorporating advanced technologies and stronger reinforcement materials.
In case of seismic events, the following actions should be taken
Inspection and evaluation: It is crucial to perform a detailed inspection to identify any visible damage, such as cracks or displacements. The assessment should include both the condition of the reinforcement and the integrity of the surrounding soil.
Repairs and reinforcements: If damage is detected, repair measures, such as sealing cracks or adding additional reinforcement to improve stability, can be implemented.
Continuous monitoring: After a seismic event, it is advisable to establish a monitoring program to observe any changes in the behavior of the wall over time.
These characteristics make reinforced soil walls a robust and adaptable option in seismically active areas.
