| 摘 要： | 基于灰色理论的GM（1,1）模型对隧道围岩变形进行短期预测,研究结果表明,隧道围岩变形差值数列的光滑性比累计变形数列的光滑性好,用围岩位移变形差值数列作为原始数列,预测精度更高。 |

| Abstract: | In this paper, the GM （ 1, 1 ） model based on grey theory is used to predict short-term deformation for tunnel surrounding rock. The results indicate that the smoothness of difference series is better than the smoothness of cumulative value of tunnel surround rock deformation. This paper use the difference series of tunnel surround rock deformation as original series, and it has higher accuracy in prediction. |
| Keywords: | tunnel surrounding rock deformation GM （1 l ） model prediction |
