However, the rule between of strength parameter （such as cohesive force and internal friction angle） and freezing and thawing cycles is not obvious with the inaccuracy of two fitting process.Furthermore， the coefficient of permeability decreases exponentially with the number of freezing and thawing cycles, and the fitting curve and equation is according with the measured values well, which prove that the uniaxial pressive strength on age 35d of lime soil treated with lime of dry mass ratio 15% is stable under freezing and thawing cycles with the water content of 24% to 26%.
