Shear strength change of different water content after thawing remolded soil

摘要

Freeze-thaw made the microstructure of the soil produce a certain degree of damage, which was relevant with the soil water content. 6 kinds of remolded soil of the water content was prepared, at low temperature of freezed, in room temperature of melt, after not consolidated non-drained triaxial compression test, the soil shear strength parameters was determined. The results show: after thawed, soil shear strength had reduced significantly, and water content exerted such a pronounced effect on strength of reducing amplitude. Accordingly, the relationship of shear strength reducing after thawing of remolded soil and the water content was set up preliminarily.
