Abstract EN
Mechanical behavior of frozen rock-soil mixture was investigated through direct shear test based on remolded specimens.
The peak shear strength of rock-soil mixture increases greatly when it is fully frozen.
The shear process goes through four stages including compaction, elastic deformation, plastic yield, and failure.
The specimen has slight compaction in vertical direction at the beginning of shear test; then it changes to dilatancy.
The temperature and ice content have vital important effect on the shear behavior of frozen rock-soil mixture.
Results indicated that the peak shear strength of rock-soil mixture increases with temperature decreasing when temperature ranges from −1°C to −16°C.
But the curve has clear inflexion at −5°C.
When temperature is higher than this degree, the peak shear strength increases sharply with temperature decreasing.
Otherwise, the rise of the peak shear strength with the decrease of temperature becomes gentle.
The shear strength of rock-soil mixture goes up first and then down with ice content increasing at −5°C for samples with initial water contents varying from 9% to 14%.
The shear strength reaches its peak value at initial water content ranging between 10% and 12% by weight.
