摘要
针对引水隧洞围岩变形监测数据的特点 ,建立了非等步长灰色模型 ,用所建模型对围岩变形的位移进行预测 ,结果表明预测值与实测值误差较小 ,说明了本模型具有较高的精度 ,可以为隧洞设计提供理论依据。
Unequal step grey model is set up based on surveyed data of tunnel rock deformation in the paper, which is used for predicting displacement of tunnel rock deformation. The predicted result has indicated that difference between predicted value and measured ralue is rather small which shows the model is accurate and could provide theory bases for design.
