摘要
在众多的曲线拟合方法中,灰色模型曲线可以用来描述路基沉降.但灰色模型有不足之处,主要是GM(1,1)预测模型是增长指数模型,具有无限增长的特性.作为能量系统,不可能出现这种现象.本文在灰色模型的基础上进行改进,提出了修正灰色模型,并将其应用于路基沉降研究.结果显示本方法能够准确地预测沉降,从而使后期施工组织安排达到最优化.
Among most curve fit methods, grey model curve can be used to describe embankment settlement. But grey model has some shortcomings, as GM( 1,1 ) is an increasing exponent model, which is of unlimited increase. This is not the case. This paper develops grey model, and offers modified grey model, and uses it to embankment settlement research. The result shows this modified method is great, and gives some reference for other line's embankment settlement prediction.
