During a tunnel excavation in a soft soil stratum, a transparent model test can present the whole failure process, and a similar transparent material with stable physical and mechanical properties is the premise for valid experimental results. Therefore, a new similar transparent material was developed, where fused quartz sand was coarse aggregate, nanoscale hydrophobic fumed silica powder was the binder, and the mixture of n-dodecane and 15# white oil was pore fluid. The developed similar transparent material's main parameters, including unit weight, internal friction angle, cohesion, and compression modulus. Further, the consistency between similar transparent material and natural soft soil was verified in three aspects: physical nature, compression strength characteristics, and shear properties. Finally, the appropriate adjustment measures were proposed based on the results of analysis of variance (ANOVA) and analysis of range (ANOR) analyses to meet the similarity demands of parameters under different engineering conditions.
Keywords: Similar material, Transparent cemented soil, Similarity theory, Soft soil stratum, sensitivity analysis, mixing proportion
