新型透明黏土的配制及其基本特性研究

Distribution and basic characteristics of new transparent clay

  • 摘要: 人工合成透明土是研究土体内部的变形及渗流情况的良好工具,传统透明土多针对砂土,且在量化透明度方面尚未形成统一的评价系统。针对上述问题,提出一种新型透明黏土——AVC透明土的配制方法,和一种透明土的透明度量化评价方法,并用该方法对比分析AVC透明土与传统透明土的透明度;开展固结试验与微型十字板剪切试验,得到该透明土的压缩固结特性与强度影响因素。试验结果表明:AVC透明黏土具有250 mm可视厚度,透明度优于传统透明土;压缩特性与天然黏土十分相似,固结系数与淤泥相似;2.5%浓度AVC透明土比4.5%浓度LAPONITERD透明土的峰值强度更高。

     

    Abstract: The synthetic transparent soil is a good tool to study deformation and seepage inside the soil. The traditional transparent soil is mostly aimed at sand, and a unified evaluation system has been not yet formed in terms of quantitative transparency. In view of the above problems, a new type of transparent clay, AVC transparent soil formulation method, and a transparent soil transparency quantitative evaluation method are propesed to compare and analyze the transparency of AVC transparent soil and traditional transparent soil. The compression and solidification characteristics and strength factors of the transparent soil are obtained. The test results show that the AVC transparent clay has visual thickness of 250 mm, and the transparency is better than that of the traditional transparent soil. The compression characteristic is very similar to that of the natural clay, and the solidification coefficient is similar to that of the silt. The peak strength of AVC transparent soil of 2.5% is higher than that of the concentration of LAPONITERD transparent soil of 4.5%.
