To study the dynamic mechanical properties of concrete after freeze-thaw deterioration, the uniaxial compression tests of concrete specimens with varied freeze-thaw deterioration degrees are carried out by 10 MN triaxial static-dynamic instrument under different loading rates. The laws of the energy release and the damage evolution are analyzed by using acoustic emission. The damage development patterns of concrete with the strain under different load combinations are studied based on the Weibull-Lognormal damage constitutive model and its fitting experimental results. The results show that:①For the concrete specimens with the same freeze-thaw deterioration degree, the peak stress increases with the increase of the strain rate, while the peak strain decreases. It indicates that the freeze-thaw deterioration degrees have influences on the sensitivity of the peak stress. ②For the concrete specimens with the same strain rate, the peak stress decreases with the increase of the number of freeze-thaw cycles, while the peak strain increases. ③The stress-strain relationship of the concrete specimens after freeze-thaw deterioration is subjected to follow Weibull statistical distribution before the peak stress, and follow Lognormal statistical distribution after the peak stress. ④For the concrete specimens with the same strain rate, the accumulative plastic strain of concrete generally increases with the increase of the number of freeze-thaw cycles.
