dc.description.abstract | The presence of unfrozen water in frozen soils considerably affects the thermal, hydraulic, and mechanical behaviors of the ground. A thorough examination and accurate estimation of the unfrozen-water saturation curve of target soil materials are required to reliably predict the behavior of frozen soils. This study presents a methodology for accurately determining the curve-fitting coefficients included in an empirical model equation. This study differentiates itself from existing research by presenting a method for easily determining the fitting curve coefficient of empirical unfrozen water saturation model through simple freezing experiment data (time-temperature data) and iterative calculation of numerical analysis. An appropriate unfrozen-water saturation curve of sandy soil specimens was obtained by conducting iterative numerical analyses based on indoor experimental data. The reliability of the determined unfrozen-water saturation curve was evaluated by comparing the simulation results for a single freeze-pipe freezing example with an analytical solution. | - |
