Study on the Physics and Mechanical Properties of Freeze-Thaw Soil and Undisturbed Soil

Abstract:

The parameter of the undisturbed soil cannot be used simply in the engineering for the characteristics varied considerably. So the physics and mechanical characteristics of freeze-thaw soil are very important in the freezing method engineering. The physics and mechanical properties of freeze-thaw soil and undisturbed soil are compared by the experiment. And the data of test are shown that after the samples are frozen and thawed, density, dry density decrease and plastic limit decrease, void ratio increase a little, other physicals are similar. Permeability of mild clay greatly increased. Compressibility of mild clay decrease, but compressibility of fine sand increase. This can be used reference to model test, numerical analysis and project designing.
