摘要/Abstract

摘要： 对土工合成纤维土（TEXSOL）的补强机理进行了理论分析，研究了各种因素对纤维土补强特性的影响规律及已有纤维土强度计算经验公式的缺陷，并在大量试验的基础上确定了一系列经验系数如K，Q，R，P等，得出了各种影响因素与纤维土补强特性的关系。研究结果表明，纤维土粘聚力的增量与纤维的韧度、细度及纤维土的配合比等参数有关；提出了能反映多种影响因素的纤维土补强计算经验公式；最后将直壁高度法推广到纤维土挡墙的设计中，并应用所提公式对纤维土挡墙进行了内部稳定分析。

Abstract: The TEXSOL reinforcement mechanism was analyzed theoretically. The influencing rule of several factors on TEXSOL reinforcement character was researched; and the defect of the existing experimental calculating formula of TEXSOL strength was analyzed. Based on a lot of experimental results, a series of empirical coefficients were determined. The relationship of influencing factors and TEXSOL reinforcement character was gained. The research shows that the increment of TEXSOL cohesive strength is related to the fiber toughness, fiber fineness and TEXSOL mixing ratio. The empirical formula of TEXSOL reinforcement was proposed. Finally, the straight-wall height method was extended to the design of TEXSOL retaining wall; and the proposed empirical formula was used to analyze the internal stabilization of TEXSOL retaining wall.

Key words: TEXSOL, intercrossing mechanism, bending mechanism, mixing ratio, fineness
