  2. ( 1 ) systematic triaxial compression tests are made for the sand reinforced by various national geosynthetics. comprehensive investigations into the interaction characteristics are also made between sand / lime fly ash and various national geosynthetics by direct shear tests and pull out tests, which can help choosing geosynthetic type and understanding the geosynthetic reinforcement mechanism ; ( 2 ) this paper is also firstly systematically presents the results of a comprehensive investigation into the interaction characteristics between lime fly ash and various national geosynthetics ; ( 3 ) by non - linear fem, the influence of the modulus of geosynthetics, the thickness of the soft ground and the width of the foundation on the effectiveness of geosynthetic reinforcement are also studied ; ( 4 ) the main conclusions are as followed : ( geotextiles are likely to be suited for projects allowing high displacement, polyester warp knitting geogrids and oriented geogrids for projects allowing medium displacement, glass fiber geogrids for projects allowing low displacement and geonets for secondary projects. ( the confining effect of fill material to act on different kinds of geosynthetics varies largely, which must be considered
