In order to enhance the evaluation accuracy of the ultimate bearing capacity of stayed cables, the influence of corrosion damage on the stayed cables was considered, the mechanical property model of corroded steel wires was established, and the mechanical properties of intact and corroded steel wires were simulated. Based on the combined action of three typical cross-section corrosion distribution models, and three typical corrosion distribution model types along the cable length direction, the corrosion degrees at different positions in the stayed cable were analyzed, and the distribution law of the corrosion in the stayed cable was studied. The Monte Carlo method was used to simulate the mechanical properties of the steel wire in the cable under different corrosion degrees, and the ultimate bearing capacity of the cable was finally obtained, as well as the number of broken wires when the stayed cable reached the ultimate bearing capacity. The correlation among the ultimate bearing capacity, the number of broken wires, the corrosion depth, and the cross-section corrosion rate of the stayed cable was statistically analyzed. The influence of corrosion distribution law was analyzed. Analysis results show that under different corrosion distribution conditions, when the corroded stayed cable reaches the ultimate bearing capacity, the sample mean difference of the numbers of broken wires may reach about three times, while the sample mean change of the ultimate bearing capacity of the stayed cable can reach about 20%. When the stayed cable reaches the ultimate bearing capacity, the number of broken wires increases with the increase of corrosion degree. But the correlation between the number of broken wires and the ultimate bearing capacity is poor, even only 0.014 under some corrosion distribution conditions. In order to ensure the safety and reliability of the stayed cable, the number of broken wires should not be used as a technical index to evaluate the bearing capacity of cables.
