| 摘 要： | 悬索桥施工过程中索塔应力的监控非常关键。基于截面内力平衡的思路，提出了考虑徐变次内力情况下结构徐变、收缩的计算方法。某跨江特大跨悬索桥的应用表明该法应用方便，计算结果可靠。

| Abstract: | It is very important to monitor the stress in tower of suspension bridge during construction. Based on the internal force balance of sections ,this paper puts forward a new method to calculate the value of creep and shrinkage. It shows that the method is very efficient in some suspension bridge. |
