以武广客运专线某路段工程实测数据为基础,先用灰色理论进行建模预测,再用弱化改进后的灰色模型进行建模预测,并分别与实测数据进行对比,结果表明,弱化改进后的灰色预测模型预测精度会有很大的提高,能够满足工程要求,从而最大限度的减少观测期数而大大的缩短工期。
Based on the measured data of a section of Wuhan-Guangzhou Passenger Dedicated Line, the model is first predicted by the gray theory, and then the model is made by the weakened and improved gray model. Compared with the measured data, the results show that the improved model The prediction accuracy of the gray prediction model will be greatly improved, which can meet the engineering requirements, thus greatly reducing the number of observation periods and greatly shortening the construction period.
