The variation of the stress-strain behavior and shear -parameters of reinforced silty sand is studied. The geotextiles
were provided at different heights in the sample and tested in unconsolidated undrained condition. Two types of geotextiles,
woven and nonwoven were used as reinforcement and the experiment was conducted at three water contents. Tests were
performed on samples prepared at OMC, dry of OMC and wet of OMC in order to study the effect of water content. The results
demonstrated that geotextile inclusion increases the peak strength, axial strain at failure. The sample was found to fail due to
bulging between the layers.
