| 摘 要： | 在灰色模型GM(1.1)的基础上,建立了非等间距灰色模型,用于高层建筑沉降预测。非等间距模型是以等间距数列为基础,把非等间距数列转化为等间距数列,再进行一次累加生成处理,进而建立GM(1.1)模型,并介绍了其精度评定的方法。结合高层建筑沉降监测工程实例进行计算分析,预测精度较高。实践证明,非等间距灰色预测模型在沉降预测中具有较高的应用价值。

| Abstract: | Based on the grey model GM(1.1),a non-spacing interval grey model is built for the prediction of subsidence in high-rise buildings.It is based on interval sequence,which is turned into a series of spacing interval sequence after accumulating procession.In this way,grey GM(1.1) model is established and the measures of assessing its precision are introduced.Computation and analysis in specific subsidence monitoring projects show that the precision of the new model is high and it can be widely applied into the prediction of subsidence in high-rise buildings. |
