摘要
探讨了模糊数学中的隶属函数理论在公路桥梁技术状态评估中的应用 ,通过比较桥梁损伤度隶属函数值的大小来确定其对应的技术状态等级 ;并通过表观检测、静力检测确定检算系数 Z,从而得出其超安全度 γ。综合模糊评判和超安全度 ,得出桥梁的最后技术状态等级。
The theory of membership function of fuzzy mathematic applied in evaluating the present bridge was discussed and the technical state grade was determined according to its value of membership function of damage value.The check-calculation coefficient Z was determined by apparent observation and static load experiment and also the super-safety degree γ was obtained.The final technical state grade can be deduced from the fuzzy judge and super-safety degree.
