摘要
通过室内固结试验和三轴试验,探讨了纤维长度及纤维土配合比对纤维土压缩性和抗剪强度的影响。结果表明:合理的纤维掺入会减小土体的压缩性;与素土相比,纤维土的抗剪强度有所提高,纤维的掺入对土体的内摩擦角和黏聚力均有影响,且随纤维长度和配合比的增加,土体黏聚力的增长更为显著。
Through laboratory consolidation test and triaxial test,the influence of fiber length and mixing ratio on the compressibility and shear strength of TEXSOL was discussed.The research shows that reasonable incorporation of fiber would reduce the compressibility of soil;In comparison with soil,the shear strength of TEXSOL has improved;The incorporation of fiber had effect on soil friction angle and cohesion,with the fiber length and the mix ratio increasing,the soil cohesion increases more significantly.
