PULL-OUT TEST ON GEOGRID IN SAND REINFORCED BY CONTINUOUS FIBERS

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...

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

Numerical Study of Cyclic Behavior of Shallow Foundations on Sand Reinforced with Geogrid and Grid-Anchor

When the foundations of structures under cyclic loading with amplitudes less than their permissible load, the concern exists often for the amount of uniform and non-uniform settlement of such structures. Storage tank foundations with numerous filling and discharging and railways ballast course under repeating transportation loads are examples of such conditions. This paper deals with the effect...

An Investigation on Behavior of Centrally Loaded Shallow Foundation on Sand Bed Reinforced with Geogrid

The study pertains to the investigation of the effect of embedment on the load carrying capacity and settlement of strip foundations on sand reinforced with geogrids. Geogrid being an inextensible reinforcing material is widely used all over the world mainly for retaining walls, abutments slope protection and below the foundation in poor soil. Some research works have been done the investigator...

Improvement of Strength Parameters of Sand Reinforced with Polymeric Fibers

Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...
