摘    要:通过直剪试验和三轴压缩试验,探讨纤维长度、细度、韧度及纤维土配合比对纤维土抗剪强度和应力-应变关系的影响。结果表明:纤维的掺入对土体内摩擦角的影响较小,主要提高了土体的黏聚力;纤维土的应力-应变关系呈应变硬化的特点,不存在典型的黏着破坏和拉力破坏;纤维的长度、韧度和配合比对纤维土应力-应变关系和抗剪强度的影响显著,纤维细度的影响相对较小。

关 键 词:土工合成纤维土  配合比  应变硬化  三轴压缩试验

Abstract: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.
Keywords:TEXSOL  mixing ratio  strain hardening  triaxial compression test
