中文摘要：
针对在役混凝土结构的主要特征、损伤状况、破坏情形及其耐久性的基本特点，将混凝土构件耐久性评定指标分为定性指标和定量指标两大类．分析定性指标中的环境条件、钢筋锈蚀程度，以及定量指标中混凝土碳化深度、混凝土保护层厚度、裂缝宽度、钢筋锈蚀量和构件承载力衰减等影响混凝土构件耐久性的因数，设计各指标的评定方法，并制定相应的评定标准．建立在役混凝土构件耐久性的系统评判模型，以供在役混凝土构件的损伤判别、耐久性失效评定．
英文摘要：
According to the major characteristics, the damage and failure of concrete structures, the durability assessment indexes of concrete members can be classified into the qualitative indexes and quantitative indexes. Based on the analysis of indexes influencing the durability of concrete, including the qualitative indexes of environment condition, rein- forcement corrosion, and the quantitative indexes of carbonization depth, cover thickness, crack width, steel corrosion rate and reduction of load carrying capacity, the assessment methods are proposed, and the corresponding model is established. The model can assess the damage and the durability of concrete members.
