Investigation on frost heave of saturated–unsaturated soils
WebJan 3, 2024 · Taking into account the coupled THM mechanism in freezing soils, a discrete ice lenses based model for frost heave is established with focus on segregation and growth of the ice lens. Upon validation of the frost heave model, an intermittent freezing method is applied to investigate mitigation of frost heave. Web2.1 Frost Heave and Thaw Weakening. Freezing soils can exhibit the phenomenon known as frost heave, whereby a gradient in the soil moisture tension is established that draws water at depth to the freezing front (the pore ice–pore water interface), where it joins the forming ice lattice. This process can force the soil particles apart to ... net use show username
