Phase Transitions in Saline Pore Water in Artificial Ground Freezing

Abstract

The influence of phase transitions in moist and salt-containing soil on freezing process is analyzed. The effects connected with the crystallization heat of pore water under negative temperatures and with the crystallization heat of salt when the eutectic point is reached are discussed. The conclusions on reachability of the eutectic point in artificially frozen strata above saline are drawn. Using a mathematical mode of heat processes in artificially frozen clay containing the common salt solution, the influence of the offset of the eutectic point on the temperature field in the frozen ground is analyzed.
