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%.
