灰色模型在工程应用中的精度探讨

Discussion of the precision about grey model in application

灰色模型就建立过程的不同可分为等时距模型和不等时距模型,对两种模型的精度进行了分析研究,最后得出不等时距GM(1,1)模型更接近于实际情况,不必进行模型修正便可对地基的未来沉降做出预测的结论。

The grey model can be devided into two kinds of models： equal time-interval model and unequal time-interval model. This paper discusses the question through engineering practice, at last finds unequal time-interval model is the more accurate one. And draws a conclusion that man can predict future settement of foundation without model correction.
