摘　　要：通过对非等步长序列数据的处理,运用传统等步长GM(1,1)模型的建模原理,建立非等步长序列的GM(1,1)模型,对高速公路隧道洞口段仰坡沉降变形进行预测和模拟。结果表明,该模型预测精度高,预测结果可靠。与传统模型相比,该方法更适用于实际监测,更具有实用价值,进一步推广了灰色系统理论在工程中的应用。Based on building traditional gray model method and processing unequal step date, the unequal step model is established, which is used to simulate and predict the side slope deformation of the tunnel outlet. The results indicate the unequal step model＇s predicting result is preeise and considerable reliability. It has more practical value and applying to practical situation than the traditional gray model. The method improves gray system theory＇s application range in the engineering project.
