摘要: Abstract The calculation model for the unfrozen water content is important in cold regions engineering, especially numerical modeling. In this study, we reviewed six models and explored effects of parameters on calculated results models. We also investigated measured subzero temperature ranges volumetric contents. It shows that significantly affect slopes, shapes contents ranges. have great impacts smaller lead to large variations contents, at lower temperatures. Among models, Kozlowski FX-Clapeyron are least sensitive indicates determined by usually perform best, From above analysis, VG-Clapeyron model, FX(C(T) = 1)-Clapeyron can be used calculate if larger range available, otherwise, content.
