Analysis of the Use of Geogrid for Soil Reinforcement in the Application of Surface Foundation

Abstract

With the development of constructions, engineering often faces the challenge of building on land with low support capacity. A solution for these cases is the soil reinforcement with geosynthetics, which by increasing the load capacity of soil, enables the use of shallow foundations. In view of this, the present work evaluates the use of the geogrid as a geotechnical reinforcement material. Therefore, a static load proof tests on the plate was performed in sandy soil, in its natural state and reinforced with the geogrid. The soil strengths were compared in both cases and the strength gained with the use of the geogrid was estimated. The results showed that the use of the geogrid could increase soil resistance by over 90%, indicating that it is an excellent reinforcement material for the soil.
