The Evolution of the Dynamic Modulus of Fly Ash Soil under the Freeze-thaw Cycles

摘要

This paper derived a damage function model of fly ash soil that under the effect of freeze-thaw cycles by using the penetration test and the basic theory of damage mechanics. The Calculated data of the model have a high degree of agreement with the measured data. This model provides a new way for the study of fly ash soil subgrade dynamic modulus in the seasonal frozen area.
