基于流体配比与颗粒粒径的透明土透明度优化研究
Transparency optimization of transparent soil based on fluid ratio and particle size
摘要
Abstract
High transparency is the prerequisite and guarantee for conducting large-scale transparent soil visualization experiments under complex conditions.In order to evaluate and configure transparent soil with high transparency,this study takes transparent soil as the research subject,with n-dodecane and No.15 white mineral oil as pore fluid and fused silica sand as aggregate.We proposed a modified for-mula for the configuration of Christensen transmissivity based on optical principles,and verified the transparency optimization method through experiments.Results indicate that:① Differences in solid-liquid refractive index and the particle size of solid particles are factors influencing transparency related to configuration of transparent soil itself.② For transparent soil samples with the thickness of 100 mm,the upper and lower limits of the differences in refractive index were±0.002 between solid and liquid.Within the theoretical temperature range of 0~50 ℃(under normal pressure),for every 1 ℃ in-crease,the refractive index of the pore fluid decreased by about 0.000 4.③ The ideal refractive index of pore fluid(1.458 5)at higher temperatures corresponded to a lower volume ratio of alkane to oil.④Transparent soil in the grade of light absorption coefficient in the colorless optical glass was between Grade 5 and 6.关键词
