Analysis of Microstructural Changes in Frozen Sandy Soil Under Confining Pressures Using Scaning Electronic Microscope

Ma Wei; Wu Ziwang; Chang Xiaoxiao and Wang Jiacheng(State Key Laboratory of Frozen Soil Engineering. LIGG, CAS,730000)  
Using scaning electronic microscope we observed the microstructural changes of frozen saturated Lanzhou sandy soil under the conditions of-5℃ and high confining pressure (0-22MPa). Combining with the macrocharacteristics of effect of confining pressure on strength behaviour of frozen soil, it is found that 1) When 0≤σ_3 8MPa, structural densification and strengthening are dominant, so that strength of frozen soil increases with increase of confining pressure, 2) When 8≤σ_316MPa, crushing appears in some particles and melting appears in the contact ice between particles, so that strength of frozen soil decreases slowly with increase of confining pressure, 3) When σ_3≥16MPa, the crushing of particles is intensified and larger cracks appear in some of granules and structure join is damaged, so that strength of frozen soil decreases suddenly with increase of confining pressure.
