| 摘 要： | 以在建某高速铁路为背景,通过对路基沉降实测数据的汇总,根据沉降曲线形态及沉降速率的差异将其分为3类.对观测数据进行等时距变换,采用灰色理论GM(1,1)模型、双曲线法、三点法对工后沉降进行预测,并对灰色理论预测模型进行精度检验.选取堆载预压期的数据作为模型原始数据,通过与实测最后一期数据的对比,发现灰色理论预测结果更接...

| Abstract: | Based on the high-speed railway,by collecting the embankment settlement experimental data,it is di-vided into three categories according to the differences of settlement curve form and settlement rate.Grey theo-ry GM(1,1)model,the hyperbolic method and three-point method are used to predict the settlement and in-spect precision of grey theory forecasting model.Adopting data of preloading period as original data,by com-paring the measured data with predicting results of grey theory,the paper shows that resul... |
