摘　　要：在传统GM(1,1)模型的基础上考虑初始条件选取的理论缺陷,提出了改进的灰色预测模型。通过在隧道开挖后上方建筑物沉降预测值与实测值的对比分析得出,该模型具有良好的精度,并具有一定的工程应用价值。Considering the theory defect of original condition selection,an improved grey prediction model based on the traditional grey GM（1,1）model was proposed.Through comparison of predicted value and actual measured value of overground building settlement after excavation of tunnel,it was found that the improved model has excellent accuracy and certain engineering application value.
