摘要
国家体育场(鸟巢)作为2008年第二十九届奥林匹克运动会的主体育场,其建筑造型和特殊的身份必将使其成为重要的文化遗产而载入史册,因此,它的结构耐久性和耐久性设计就显得尤为重要。详细介绍了国家体育场混凝土结构耐久性使用年限、环境分类及环境作用等级、混凝土及混凝土组分设计、钢筋保护层厚度、裂缝控制、施工要求、使用阶段的维护与检修、结构耐久性寿命预测等耐久性(100年)的设计内容。
As the main stadium of 29th Olympic Games in 2008, the National Stadium Beijing（NSB）, also known as ＂Bird＇s Nest＂, is famous for its avant-grade shape and special identity, it will naturally go down in history as an important cultural heritage. Because of that, the importance of the durability of the structure and the durability of the structure design have been enhanced to a very high degree. This paper systematically introduces the durability design of concrete structure of the National Stadium, in which the durability working life of NSB, environment class, environmental action grade, concrete component design, concrete cover to reinforcement, control of concrete crack, measures of construction, maintenance and inspection, durability life prediction are elaborated.
