在公路隧道新奥法设计和施工中，精确模拟预测隧道围岩收敛位移对于合理提供公路隧道设计与施工参数具有重要的意义。结合朱洋公路隧道围岩收敛变形数据的模拟，对 DGM（1，1）模型在工程中的适用性进行了研究。经计算发现，有必要根据数据的特点选择不同的灰色模型来模拟；在隧道围岩收敛数据接近全指数增长时，用 DGM（1，1）模型能够更精确地模拟隧道围岩收敛数据。结论对于公路隧道信息化设计和施工具有参考意义。

In design and construction of New Austrian Method about highway tunnel,it has an im-portant significance to simulate convergent deformation of highway tunnel surrounding rock accurately for providing parameters of tunnel design and construction reasonably.In this paper,based on simulation of surrounding rock convergent deformation about Zhuyang highway tunnel,the applicability of DGM(1 ,1 ) model in the field of engineering is studied.The calculation results can show that,based on data charac-teristic,it is necessary to choose different grey model.When surrounding rock convergent deformation data is similar to a pure exponential sequence,DGM(1 ,1 )model can be used to simulate surrounding rock convergent deformation data more precisely.The conclusion has certain reference significance for highway tunnel information design and construction.
