Study on the mechanism of crystallization deformation of sulfate saline soil during the unidirectional freezing process
Abstract The freezing of sulfate saline soil involves the coupling effect of heat and mass transfer and crystallization deformation. The influence of salt content and temperature on the crystallization of ice and salt was analyzed by using a one‐side freezing experiment. Based on the effect of solut...
