英文摘要	In winter, hydraulic concrete is often under the synergistic destruction of the freeze-thaw cycle, dry-wet alternation, and salt erosion. The special climate in cold and arid areas has adverse effects on the safe operation and economic benefits of hydraulic buildings. The durability of polypropylene fiber-modified concrete under multiple working conditions was studied. Combined with the FOTP-GM (1,1) model, damage prediction of modified concrete under different working conditions was carried out. The results show that a certain amount of polypropylene fiber significantly increased the corrosion resistance of specimens. The fitting degree between the measured sequence and the model increased with increasing order 'h' of the time power term. Under different working conditions, the time power term corresponding to the optimal model structure was different. The correlation coefficient R-2 between the established prediction model and the original sequence was above 0.9. Through error analysis, it was proved that the FOTP-GM (1,1) model can effectively predict the number of cycles when the concrete reaches the failure standard. The optimal model structure can be used in practical engineering to establish a prediction model to calculate the safe 0service life of engineering structures.
