Deformation of Geotextile confined in Soil

Abstract

The laboratory pull-out test of the nonwoven fabric confined in sand was performed to examine the deformation of the geotextile confined in soil. As a result, because the lateral contraction of the nonwoven fabric decreases as normal stress increases, it was able to estimate that the lateral contraction will not develop as the lateral contractible force of the nonwoven fabric is equal to the friction between soil and nonwoven fabric. In additions the distribution of shear stress occurred between the geotextile and the soil was examined by the mechanical model. As the result of analysis, it is examined that the distribute condition of shear stress will be controlled strongly by the modulus of rigidity of the geotextile.
