【摘要】 以太原市太行路阎家峰路段的黄土高填方路堤工后沉降监测数据为基础资料,根据路堤堤身沉降特点,将其分为前期沉降和后期沉降,然后利用均值GM(1,1)模型分别对这两个时期的实测数据进行灰色建模,得到相应预测值,然后利用灰色系统理论中的接近关联度模型对灰色预测模型的可靠性进行检验,结果分析表明:均值GM(1,1)模型预测结果可靠,并且灰色预测模型特别适用于针对路堤后期的沉降数据进行建模,从而对路堤未来沉降量进行较准确的预测。更多还原

【Abstract】 Based on the monitoring data of Post-construction Settlements about high loess embankment at the Yanjiafeng section of Taihang Road project in Taiyuan and the characteristics of embankment settlement,it can be divided into early settlement and later settlement. The corresponding forecasting data of the two periods can be get by GM( 1,1). The reliability of the GM( 1,1) can be tested by the closed Grey relativity analysis. The results showed that the GM( 1,1) is reliable and it is especially suitable for the latter settlement. Thus,it can be gained more accurate predictions for the future embankment settlement.更多还原
