［摘要］國(guó)家體育場(chǎng)(鳥(niǎo)巢)作為2008年第二十九屆奧林匹克運(yùn)動(dòng)會(huì)的主體育場(chǎng)，其建筑造型和特殊的身份必將使其成為重要的文化遺產(chǎn)而載入史冊(cè)，因此，它的結(jié)構(gòu)耐久性和耐久性設(shè)計(jì)就顯得尤為重要。詳細(xì)介紹了國(guó)家體育場(chǎng)混凝土結(jié)構(gòu)耐久性使用年限、環(huán)境分類及環(huán)境作用等級(jí)、混凝土及混凝土組分設(shè)計(jì)、鋼筋保護(hù)層厚度、裂縫控制、施工要求、使用階段的維護(hù)與檢修、結(jié)構(gòu)耐久性壽命預(yù)測(cè)等耐久性(100年)的設(shè)計(jì)內(nèi)容。

Durability design of concrete structure of the National Stadium
You Tianzhi，Tang Jie(China Architecture Design and Research Group, Beijing 100044, China)Abstract: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.
Keywords:concrete structure durability; environment class; action grade; concrete component; cover to reinforcement; control of crack; construction measures; maintenance and inspection; durability life prediction
