Abstract

Abstract

To explore the laws of fatigue damage for cement-solidified soil under the action of freeze-thaw cycle, the failure modes of strength for cement-solidified soil were defined based on analysis of the stress-strain curves for cement-solidified soil with different mass fractions of cement mix. The development processes of internal defects in freeze-thaw damage were analyzed, combined with the results of freeze-thaw damage tests. Taking elastic moduli as damage indexes, a freeze-thaw damage model of the cement-solidified soil characterized by elastic moduli was proposed. According to the model, the test data were fitted and the values of test parameters were obtained, the proposed model was checked by test results from other regions and in different test conditions, the results showed that the model could reflected the laws of fatigue damage for cement-solidified soil under the action of freeze-thaw cycle.
