Group effect on soil arching in geogrid-reinforced pile-supported embankments

Bridge foundations supported by EPS geofoam embankments on soft soil

EPS geofoam can be used to support highway bridge structures without the aid of deep foundations. The development of this technology is important to accelerate construction on soft compressible soil. EPS geofoam allows for the rapid construction of bridge foundations on such soils without the time and cost involved in installing traditional foundations. Because EPS geofoam is an extremely light...

A Simplified Method for Analysis of Geosynthetic Reinforcement Used in Pile Supported Embankments

The inclusion of geosynthetic reinforcement in the piled embankment can help transfer loads to the piles and reduce total and differential settlements. In order to select the appropriate reinforcement material, the reasonable calculation of the deflection and tension is very important. Current design methods usually do not represent the true three-dimensional (3D) nature of the displacements, s...

Effect of Geogrid Aperture Size and Soil Particle Size on Geogrid-Soil Interaction under Pull-Out Loading

Eccentrically loaded strip foundation on geogrid-reinforced sand

Results are presented for laboratory model tests conducted to determine the ultimate bearing capacity of an eccentrically loaded strip foundation supported by geogridreinforced sand. Only one type of sand at one relative density of compaction and one type of geogrid were used for the tests. The depth of the foundation was varied from zero to B (width of foundation). Based on the laboratory test...

3D FEM Analysis of a Pile-Supported Riverine Platform under Environmental Loads Incorporating Soil-Pile Interaction

An existing riverine platform in Egypt, together with its pile group foundation, is analyzed under environmental loads using 3D FEM structural analysis software incorporating soil-pile interaction. The interaction between the transfer plate and the piles supporting the platform is investigated. Two connection conditions were studied assuming fixed or hinged connection between the piles and the ...
