| Abstract: | The formation and development of microstructure in frozen,freezing and thawing soil under different teperatures and overburden pressures are studied by scanning electronic microscope. Results show that the scanning electronic microscope is a good tool for the study in many aspects such as soil particle moving aggregating and separating, morphology of unfrozen water membrane, mechanism of crryogenic structure and dislocation and craking of soil particles under different overburden pressures. |
