Abstract: Dynamic triaxial tests were conducted on the renforced soils with 5% lime conetent. Such dynamic properties as cumulative palstic strain, dynamic strain, dynamic stress and resilient module with the cycle times were studied. Based on the test results, the critical dynamic stress of the lime-stabilized soil, the regression coefficients of the correlation between the cumulative plastic strain and cycle time, and the regression coefficients of the correlation between dynamic stress and strain were obtained.
