| 摘 要： | 以在编的《混凝土结构耐久性设计规范》为背景,讨论和分析了耐久性设计中混凝土结构钢筋保护层厚度取值和质量要求,并与现行的国际混凝土规范取值进行了比较.然后,明确了耐久性设计中最小保护层厚度与名义保护层厚度的定义与各自的适用范围,讨论了耐久性保证率和保护层厚度保证率的关系.最后,结合我国工程实际的保护层调查数据,对耐久性设计中混凝土保护层允差的取值进行了探讨.

| Abstract: | Based on the technical writing of Chinese national code on durability design of concrete structures, the specification on the concrete cover and quality is investigated and compared with other codes in use. Then, the authors discuss the definitions of minimum cover and nominal cover as well as their respective application cases. With the in field investigations in China, the construction tolerance for concrete cover is proposed in the end. |
