摘要
Abstract
Based on the high-speed railway,by collecting the embankment settlement experimental data, it is divided into three categories according to the differences of settlement curve form and settlement rate. Grey theory GM(1,1) model, the hyperbolic method and three-point method are used to predict the settlement and inspect precision of grey theory forecasting model. Adopting data of preloading period as original data, by comparing the measured data with predicting results of grey theory, the paper shows that results of grey theory are more close to measured values. GM( 1,1) model prediction can get more satisfactory results.关键词
