The freezing process of salinized soil is a complex, dynamic, and interactive hydro–thermal–salt–mechanical (HTSM) coupled physical phenomenon. In many recent studies, was assumed to be saturated, the theoretical models established were based on framework saturated soil, in which influence vapor phase neglected. this paper, by considering effect flow heat movement relation between saturation void ratio, an improved mathematical model will previous research. This (IHTSM) simulates dynamic...
Freezing in saturated saline soil is a dynamic, coupled hydraulic-thermal-salt-mechanical (HSTM) process. The aim of this paper to establish model describe the coupling In model, mass conservation law, Darcy's and energy law are applied. Clapeyron equation used illustrate phase equilibrium multiphase system soil, ice, water, which contributes simplification soil-water potential. A freezing experiment using 20-cm column with top-side was performed, solved transient finite elements. numerical...
Water and heat interact in the process of freezing for saturated soil. And salinized soil, water, heat, salt process, because soil has soluble salt. In this paper, a one‐dimensional mathematical coupled model hydraulic‐thermal‐salt is established. model, Darcy’s law, law conservation energy, mass are applied to derive equations. Consider that column subjected condition moisture migration transport. Both experiment numerical simulation under same developed column. Then content between...
The existence of structural strength in undisturbed soil results its distinct characteristics compared to remolded soil. Under the influence freeze–thaw cycles, this difference may easily cause geotechnical disasters cold regions. This study aimed analyze and discuss expression degree influencing factors expansive unconfined compressive (UCS) test, high-pressure consolidation microscopic test were performed on retrieved from a seasonally frozen region. Moreover, sensitivity parameters,...
The development of agriculture and ecology, the construction water conservancy facilities are seriously hindered by salinization seasonal frozen soil. Unfrozen exists in freezing thawing This unfrozen is core foundation for studying process soil salinization. However, it difficult to obtain content (UW) routine experiments, shows nonlinear characteristics under action main factors contained: salt content, temperature. In this paper, a new model proposed predict UW saline based on combined...
