| 摘 要： | 在斜拉桥的施工监控过程中,当主梁标高和施工索力出现了偏差,对主梁应力与成桥线形造成不利的影响时,有必要采用斜拉桥施工过程中的多索力调整来消除此误差。本文结合某斜拉桥实例来阐述超重系数的确定、多索力调整的方案制定及索力优化的方法等。

| Abstract: | When a great amount of deviation of the elevation of main girders or cable force emerged during construction it would have a bad effect on the stress of main girder and the elevation in completion state of bridge.Therefore,we need to make adjustments to the multi-cable-force of cable-stayed bridge which is under construction.This paper presents the method for identification of the main girder segment weight,,as well as the schemes of multi-cable-force adjusting for this cable-stayed bridge. |
