摘　　要：对既有的金属结构非线性锈蚀模型进行了修正,提出了更加符合实际的锈蚀模型,通过实测数据的验证,修改后的模型能够真实的反应出金属锈蚀的全过程,并运用修改前后的锈蚀模型,对比分析了锈蚀引起的水工钢闸门构件抗力衰减情况和可靠度变化情况,为水工钢闸门结构的可靠性研究奠定了基础。In this paper ,it makes some correction on the existing nonlinear model of corrosion,come up with a more character and practical model of corrosion,and the actual detection data show that the modified model can true reflect the whole process of metal cor-rosion,and compare the resistance deterioration law and the time -dependent reliability of the component of the hydraulic steel gate by the existing model and the modified model,which lays the foundation for the study of reliability of Hydraulic steel gate structure.
