Three kinds of concrete panel specimens with different water cement ratio were made respectively, on the basis of the ultraviolet radiation test, specimens without uv radiation were used as a control group, and the freeze-thaw cycle test on each specimen irradiated with ultraviolet radiation at the same time for each group . The quality and dynamic modulus of the specimens are measured at regular intervals. According to the results of the test, a freeze-thaw cycle damage degree model considering ultraviolet radiation is established by the fitting analysis. The results showed that under a certain number of freeze-thaw cycles, the smaller the water-cement ratio and the lower the mass loss rate is, the higher the relative dynamic elastic modulus is, the better the frost resistance of the concrete is. Compared to the control group without ultraviolet radiation, the mass loss rate was greater after a certain number of cycles of freezing and thawing . Ultraviolet radiation effect on low strength concrete mass loss is mainly reflected in the early days of the freeze-thaw cycle, and of high strength concrete is expressed in the late stage. The obtained freeze-thaw cycle damage model is a good way to reflect the evolution of the frozen and melt cycle of the concrete with ultraviolet radiation.
