The Influence Law of Freeze-thaw Temperature Difference for the Strength Parameter of Remolded Loess

摘要

At present, the research is not enough for the correlation of loess strength parameter and freeze-thaw temperature difference in domestic. The paper aims how the change of freeze-thaw temperature difference influence the stress characters of remolded loess by consolidated drained triaxial shear test for. The results showed that: the strength parameter of remolded loess decreases with the increasing of freeze-thaw temperature difference. The reduce of strength parameter c is obvious with the increasing freeze-thaw temperature difference. The reduce of strength parameter Φ is not obvious with the increasing freeze-thaw temperature difference.
