Shear Strength Behavior of Different Geosynthetic Reinforced Soil Structure from Direct Shear Test
This paper presents the results of direct shear test on soil samples reinforced with geosynthetics, conducted with the aim of characterize the shear strength of reinforced soil composite. Two types of granular soil (well graded sand and silty sand) and four types of geosynthetic (woven and nonwoven geotextile—uniaxial and biaxial geogrid) were selected. Laboratory testing program were performed in two shear boxes, circular box with 63 mm in diameter and square box with 100 mm in length; the samples were made with loose and dense sand; the reinforcement layer was placed perpendicular to the failure surface; tests are conducted with three vertical confining pressures: 15.7, 31.4 and 62.8 kPa. The effect of different factors that influence the results of the shear tests is analyzed, such as: the particle size of soils, density of soils, shear box size and type of geosynthetics. The test results reveal that the maximum value of shear strength improvement was achieved for dense silty sand samples reinforced with biaxial geogrid. In general, the improvement was more favorable for samples reinforced with geogrid compared to samples reinforced with geotextile.Fil: Useche Infante, Danny Jose. Universidad Tecnológica Nacional.

Behavior of Rigid Circular Shallow Foundations on Geogrid-Reinforced Sand
This paper presents the effect of two types of geogrid inclusion on the bearing capacity of a rigidcircular footing resting on sand. The improvement achieved with uniaxial and biaxial geogrids iscompared. Load tests were performed for a broad series of conditions, including unreinforcedcases, was tested by varying variables such as geogrid type, number of geogrid layers, depth totopmost layer of geogrid and the case when the geogrid is anchored to the test mold. The resultswere then analyzed to find both qualitative and quantitative relationships between the bearingcapacity and the geogrid variables. The results of the investigation indicate that both, thesettlement and the bearing capacity, of circular footing resting on sand, can be enhanced by thepresence of geogrid layers. The improvement in stress-strain behavior of the geogrid-reinforcedsand was found to be strongly dependent on the number of geogrid layers, vertical distancebetween the base of the foundation and the first layer of geogrid and the tensile strength of geogridreinforcementFil: Useche Infante, Danny Jose.

Scale model to measure stress under circular footings resting on sand
This paper presents the results of a series of load tests carried out with a foundation model supported by sand. The aim of this study is to measure the stresses in the soil that occur when applying loads with a circular foundation model. Sand was placed in a circular tank of 60 cm in diameter and 45 cm in height. Diaphragm load cells were used to measure the stresses. It was used to determine the effect of the relative density in the vertical distribution of stresses in the sand. The stresses measured with the load cells were compared with those estimated with the Boussinesq?s method and were validated using a finite element model. The results showed that the inclusion of cells in the soil produced an alteration in the stress?settlement behaviour of circular footing resting on sand. Boussinesq's method presented an acceptable approximation to the stresses measured with the load cells.Fil: Useche Infante, Danny Jose.
