In our engineering practice, we used the grey theory to establish unequal time - span GM (1, 1) to forecast the settlement of soft clay foundations and the accuracy was greatly improved.
利用灰色理论建立不等时距GM(1,1)模型，对软土地基沉降进行预测，取得了较高的准确度。
GM (1, 1) model of unequal time span forecast of ground settlement is established based upon Grey theory. The result can be amended.
应用灰色理论，建立了不等时距的地基沉降预测GM(1, 1)模型，并可对结果进行修正。
