Abstract: Now, theoretical research on geosynthetic reinforcement lags behind engineering practice. In order to help choosing geosynthetic type and comprehending the geosynthetic reinforcement mechanism, systematic triaxial compression tests were made for the sand reinforced by five kinds of geosynthetics. It was obtained different effects of various geosynthetics on the shear strength and the stress-strain behaviors of the sand. Experimental results show: (1) the stress and strain tendency of the sand reinforced by various geosynthetics is different; (2) geotextiles are likely to be suited for projects allowing high displacement, PET warp knitting geogrids and oriented geogrids for projects allowing medium displacement, glass fiber warp knitting geogrids for projects allowing low displacement and geonets for secondary projects; (3) the confining effect of sand to act on different kinds of geosynthetics varies largely.

Key words: geosynthetics, reinforcement, stress and strain, confining effect, triaxial compression tests
