| Abstract: | Though experimental studies of the physical and mechanical properties of soil and freezing thawed soil respectively,conclusion was drawn with regard to the changes of physical and mechanical properties of the freezing thawed soil.Apparent increases were witnessed in porosity ratio,compression coefficient and permeability with decreases in uni axial and tri axial shearing resistance.Simultaneously,comparative analyses were conducted into the settlement mechanisms and treatments of the treezing thawed soil. |

| Keywords: | soil freezing and melting physical property mechanical property settlement experiment |
