Análisis de factores influyentes en el refuerzo de suelo cohesivo drenado usando geo sintéticos, aplicado a cimentaciones superficiales, a través del método de elementos finitos

The selection of shallow or deep foundations for infrastructure projects depends on several factors, including the characteristics of the foundation soil, which will lead to allowable bearing capacities as well as acceptable deformations in accordance with current building codes. Typically, deep foundations are used to transmit the loads of the superstructure to strata with better characteristics; however, the cost associated with this type of solution can be high, to the point of making certain types of projects unfeasible, which has led to the diversification of foundation alternatives, including soil improvement with geosynthetics. In this research, an analysis of the factors that have the greatest influence on the bearing capacity of a cohesive soil improved with geosynthetics under drained conditions was carried out through finite element modeling using Plaxis 2D software. Among the factors affecting bearing capacity and associated with the inclusion of geosynthetics are: modulus of elasticity of the reinforcement material, number of reinforcement layers, layer spacing, location of the first layer and total depth of reinforcement. These parameters were used in order to find an optimal arrangement of the reinforcement layers and to identify the behavior of the bearing capacity with the variation of these parameters. The results of the investigation show a clear tendency to improve the bearing capacity with the inclusion of geosynthetics, showing a satisfactory behavior when using this improvement method with small width footings.
