| 摘 要： | 应用灰色理论原理,建立了等维新信息GM(1,1)法预测路堤沉降模型,通过对无规则的数据序列作等距处理和微分拟合,验证和丰富了非等时距等维新信息GM模型理论,等维计算了信息变化情况下的沉降值,从而对软基路堤沉降进行较精确预测。

| Abstract: | On the basis of principle of greytheory,the model for forcasting the settlement of embankment by equal sequence new information GM(1,1) method has been established.Through treatment of irregular data sequence in equal interval and differential fit of it,the theory of GM model of equal sequence new information with unequal time-distance is verified and enriched,the settlement value under information variation is computed by equal sequence and more exact forcasting the setllement of weak foundation embankment is completed. |
