Abstract: The grey systems theory applied in continuous rigid frame bridge construction control is discussed in this article. The auther makes the practice of the construction control for Jialing jiang river bridge in Baiguodu as an example. Combined with the construction control, this paper introduces the basic principle, specific execution procedures and the application validity of this gray predictive control system. This conclusion can be extended to be used in the construction of the continuous beam bridge,the arch bridge, the cable-stayed bridge etc, which constructed by cantilever erection.

Key words: gray system theory, continuous rigid frame, construction control, predictive control

摘要： 笔者在本文以白果渡嘉陵江大桥施工控制的具体实践为例,探讨了灰色系统理论在连续刚构桥施工预拱度控制中的应用情形.结合该桥的施工控制过程,介绍了灰色预测控制系统的基本原理、具体实践步骤以及应用的有效性,这个结论可推广到采用悬臂法施工的连续梁桥、拱桥、斜拉桥等的施工.
