| 摘 要： | 考虑到构件耐久性损伤对桥梁承载能力的影响，引入了耐久性最弱截面的概念，并以混凝土缺损、混凝土碳化、裂缝、混凝土强度和钢筋锈蚀等五个方面作为衡量耐久性损伤的影响因素，尝试采用层次分析法确定耐久性最弱截面的计算方法．并以一实桥拆除构件为例，验证了该方法的可行性，

| Abstract: | The concept of the weakest section of durability is presented considering the influence on durability damage to bearing capability of bridge.Concrete defecive state, crack,carbonation,intensity and rebar corrosive level are put forward as influence factors of durability damage.Analytic hierarchy process is applied in ascertainting the weakest section of durability.Feasibility of this calculating method is testified through destructive test of bridge members dismounted from a bridge. |

| Keywords: | existing reinforced concrete bridge durability damage the weakest section of durability analytic hierarchy process |
