| 摘 要： | 运用灰色系统理论,建立大跨度预应力砼刚构-连续组合梁桥悬臂浇筑施工梁段立模标高预测的GM(1,1)模型,并用残差的GM(1,1)模型对其进行修正;同时把该预测模型应用于松原龙华松花江特大桥实际工程;其结果表明梁段立模标高预测精度较高,完全能够满足工程的需要,为同类桥梁的施工监测提供参考。

| Abstract: | A gray model(GM(1,1)) for predicting the camber level of long-span PC(pre-stressed concrete) continuous rigid frame bridge was established by using grey system theory.After being modified with residual GM(1,1),it was applied to the project of Longhua Songhuajiang Long-Span Bridge.The result shows that the prediction has a high accuracy and completely meets the requirements of the project.This method provides reference for the construction monitoring of the bridges with the same type. |
