TEST RESEARCH ON GEOTECHNIQUE TEXTILE SOIL ENGINEERING CHARACTERISTICS

Through direct shear test and the triaxial compression test，the influence of fiber length，fineness， toughness，and mixing ratio on the stress strain curve and shear strength of textile soil ( TEXSOL) was discussed． The research showed that the influence of fiber incorporation on soil internal friction angle was small，and it mainly improved the soil cohesion; the stress-strain relationship of TEXSOL showed strain hardening characteristic，there was no typical adhesive failure and tensile failure; the influence of fiber length，toughness，and mixing ratio on the stressstrain curve and shear strength of TEXSOL was remarkable，and that of fiber fineness relatively small．
