混凝土结构连续施工技术在首都机场的应用

Application of Continuous Constructing Technique to the Concrete Structure of Capital Airport Project

本文介绍首都机场3号航站楼2号飞机滑行道桥在超长钢筋混凝土墙体中使用膨胀加强带及增加温度应力钢筋提高混凝土自身的抗拉性能,控制混凝土收缩裂缝的技术措施。

This paper has presented the technical measures for shrinkage crack control of concrete in over-length reinforced concrete wall of No.2 Aircraft Running Lane Bridge No.3 Freight Forwarding Building of Capital Airport. In the practice, expansive strengthening belts were used and temperature stress steel bars were added to enhance the tension resistance ability of the concrete.
