... by accounting for soil confinement, strain compatibility between soil and geosynthetic, and soil-geosynthetic interaction. Tests using a woven geogrid, woven geotextile and needle-punched nonwoven geotextile in sand showed that ignoring interface slippage (though small) overestimates tensile loads...

...J. Zhou; J.-F. Chen; J.-F. Xue; J.-Q. Wang ABSTRACT: To study the interaction between sand particles and geogrids, pullout tests were performed on one type of geogrid in Pingtan medium sand. The sand motion around the ribs was captured by high-resolution digital camera and CCD camera. The images...

..., soil type, geosynthetic tensile stiffness, and surface characteristics. Mechanisms of interface failure and of load transference between different layers are also identified and discussed. Technical Paper by E.M. Palmeira, N.R. Lima, Jr., and L.G.R. Mello INTERACTION BETWEEN SOILS AND GEOSYNTHETIC...

...P.C. Lopes; M.L. Lopes; M.P. Lopes This paper reports the investigation of the shear behaviour of six geosynthetics with two granular soils. The test equipment, soils, and geosynthetics properties are described and the soil-geosynthetic interaction behaviour is studied. The influence of soil...

...M.J. Lopes; M.L. Lopes This paper reports the results of pullout tests on five different geosynthetics embedded in two different granular soils. Soil and geosynthetic properties are described and soil-geosynthetic interaction behaviour is studied. Based on the results of pullout tests...

... interface relationship between shear stress and shear displacement interaction. Such a description of interface strength and stiffness characteristics is needed in analytical models used to predict a displacement response of geosynthetic-reinforced soil structures. Due to the extensibility of geosynthetics...

... and geogrid properties are also fully described and the soil-geogrid interaction behaviour is studied. The conclusions of this study are as follows: the pull-out tests are reproducible; the influence of the geogrid specimen length on the geogrid specimen pull-out response is a function of the density...
