为了克服灰色模型以上以等时距原始数据作为前提条件的缺点,对灰色模型进行了改进,建立了不等时距的预测模型,将不等时距灰色模型应用于某烟囱基础沉降预测中。通过沉降预测与实际监测值对比表明,不等时距灰色预测模型精度较好,可以运用到实际工程中。 In order to overcome the shortcomings of the gray model above based on the isochronous original data, the gray model was improved and the prediction model with unequal time and distance was established. The gray model with unequal time interval was applied to the prediction of foundation settlement of a chimney. The comparison between settlement prediction and actual monitoring results shows that the gray prediction model with unequal time-lapse has better accuracy and can be applied to practical engineering.
