摘　　要：以某连续刚构桥为工程背景,建立该桥的有限元模型,并采用灰色预测控制系统对其进行线形控制,通过对线形控制的理论预测值和实测值比较分析,说明灰色预测控制系统能较好地应用于此类桥梁的线形控制。This paper＇s engineering background is a concrete continuous rigid-frame bridges of railway. The bridges＇ finite element model has been set. And the grey prediction theory is used to the linear control. Through comparing the prediction to the measured value, we can get that this theory is applied to this kind of bridges＇ linear control.
