Frost depth prediction for seasonal freezing area in Eastern Turkey

Abstract

This paper presents the results of an investigation relative to the prediction of frost depths of seasonal freezing area in eastern Turkey. The Stefan equation and a modified Berggren equation are compared and utilized, and the computed results are compared with actual observed data. Also, the different harmful effects of freezing-thawing on highways in eastern Turkey are elucidated, supplemented with case studies. Based on this, the coldest areas are defined and a freezing depth contour map with the region's transportation network is produced. Some recommendations for the design and maintenance of subgrades in cold regions are provided.

“…In addition to those listed in Table 2 in the original article, Table 1 shows further index properties of the materials that composed the reconstructed foundation layers [i.e., clayey sand subgrade, recycled portland cement concrete pavement-recycled asphalt pavement (RPCC-RAP) subbase, and RPCC subbase]. There are alternative methods to determine the thermal properties of geomaterials (Bianchini and Gonzalez 2012;Orakoglu et al 2016;Zhang et al 2018a). In the original study, empirical correlation-based geomaterial dry unit weight and moisture content were applied.…”

Simulating the freezing-thawing processes based on MODIS data in the Three-River Souce Region, China

“…The presence of ice in the soil reduces the infiltration capacity, which leads to a higher percentage of snowmelt and spring precipitation being partitioned into surface runoff and thus influences the hydrological cycles (Cherkauer and Lettenmaier, 2003;Jiang et al, 2013;Orakoglu et al, 2016). It also influences the timing of spring runoff and the amount of soil moisture (Koren et al, 1999).…”
