在研究钢筋锈蚀过程的基础上引入4个耐久性因子DF(Durability Factor),进行了构件基本参数关于耐久性因子的敏感性分析,由此得到构件不同基本参数偏离设计值对耐久性的影响程度.该结论可指导桥梁耐久性设计和桥梁施工.
Based on the analysis of steel corrosion course, four durability factors are introduced. The sensitivity analysis of basic parameters on the durability factors is carried out. All the results show that different basic parameters deviating from the design value influence the durability. The result could be useful to predict the durability for the design and construction of bridges.
