用灰理论预测预应力混凝土斜拉桥节段立模标高方法探析

Forecasting Segment Construction of Prestressed Cable-Stayed Bridges in Gray Theory

运用灰理论的基本原理分析了斜拉桥施工控制的灰性表现,用等间距或不等间距的GM(1,1)模型预测了一座在建的跨黄河的三塔四跨斜拉桥的中跨主梁的部分节段的立模标高,并将预测结果与用另一种方法计算得到的结果做了比较。

In this paper the gray characters of construction control for cable-stayed bridges are analyzed on the basis of gray theory. The elevation of form board of partial beams in middle span of a cable-stayed bridge with three towers and four balks being built on Yellow River is predicted by means of GM(1,1) model with equal or unequal intervals and the predicted result is compared with the result gained from a different computing methods.
