“…Freeze-thaw cycles(FTCs) as a commonly weathering action that can occur more than 100 times within a year for the geological body in cold regions [ 1 ], which can change the properties of the soils and cause the engineering problems. Such as frost heave deformation [ 2 , 3 ] and thaw slumping [ [4] , [5] , [6] ], frost heave cracking of lining [ [7] , [8] , [9] ] and thermokarst [ 10 , 11 ]. Besides, the FTCs also can trigger many disasters including landslides and debris flow [ [12] , [13] , [14] ].…”

“…Since then, numerous experimental and theoretical efforts have been undertaken to systematically investigate the frost heave characteristics of a variety of soils, including the mechanism, amount, and pressure [4,[6][7][8]. Various methods have been proposed to describe the frost heave process, such as the capillary model [9], rigid ice model [10][11][12][13][14], segregation potential model [15], thermomechanical models [16], and semi-empirical approaches [17,18]. In addition, recent research interests in frost heave and frost action in frost-susceptible soils have been renewed in China [19,20].…”

In analyzing frost heave, researchers often simplify the compressive modulus of freezing soil by considering it as a constant or only as a function of temperature. However, it is a critical parameter characterizing the stress–strain behavior of soil and a variable that is influenced by many other parameters. Hence, herein several one-dimensional freezing experiments are conducted on silty clay in an open system subjected to multistage freezing by considering the compressive modulus as a variable. First, freezing soil under multistage freezing is divided into several layers according to the frozen fringe theory. Then, the correlation between the freezing rate and temperature gradient within each freezing soil layer is investigated. Takashi’s equation for frost heave analysis is modified to extend its application conditions by replacing its freezing rate term with a temperature gradient term. A mechanical model for the stress–strain behavior of freezing soil under the action of frost heave is derived within the theoretical framework of nonlinear elasticity, in which a method for determining the compressive modulus of freezing soil with temperature gradient, overburden pressure, and cooling temperature variables is proposed. This study further enhances our understanding of the typical mechanical behavior of saturated freezing silty clay under frost heave action.

“…Empirical models that are easy to be used are based upon curve fitting of frost heave experiments [26], e.g., the modified Takashi model [27]. However, the complex migration of both heat and water and the ice segregation criterion cannot be well reflected by a single parameter, e.g., the discontinuous ice lens.…”

Soil frost heave acts as a driver of the emerged fracture in the concrete lining of irrigation canals and subsequent water leakage in seasonal frozen ground. A model test was carried out on the frost heave of a U-shaped canal with concrete lining. The heat and water migration during freezing, and frost heave-induced deformation, and force in normal direction were live monitored by high-precision transducers. The results prove that the freezing front descends downward over time at a specified thermal boundary, with considerable migration of water within the scope of 0–40 cm. The maximum deformation occurred at the bottom of the lining and decreased upward with the rate of frost heave lowering over time while the normal force showing little change in the monitoring points, implying that stress concentration does not show up during freezing. Besides, the layered settlement observation reveals that frost heave dominates the total deformation while creep, the universal source of deformation, accounts for a negligible proportion. A practical model was proposed based on a simple theoretical model for heat-water coupled transfer in a partially saturated medium and was numerically implemented in COMSOL. The computed results were compared with the monitored data including frozen depth, water content, normal displacement, and frost heave force. Finally, the rational thickness of the insulation board was determined based on the partial insulation method.
