灰色系统理论在巴河大桥施工控制中的应用

The Application of the Grey System Method in Construction Control of Ba River Bridge

预拱度的控制是连续刚构桥施工控制中的重要组成部分.以某大跨径连续刚构桥施工控制具体实践为基础,以灰色系统理论GM(1,1)新陈代谢模型为理论依据,探讨了连续刚构桥施工预拱度控制中灰色系统理论的具体应用,监控实践中预测数据与现场实测数据吻合良好,实践证明该方法能够优化预拱度控制,指导连续刚构桥施工.

Pre-camber control is an important part in the continuous rigid frame bridge construction control, the text of a long-span continuous rigid frame bridge construction control specific practices based metabolic model theory of gray system GM （ 1,1 ） as a theoretical basis for the specific application of gray system theory in the con- trol of continuous rigid frame bridge. Pre-camber forecast data and field measurement monitoring practice in good agreement with the practice has proved that the method is able to optimize the control of the pre-camber, guiding continuous rigid frame bridge construction.
