摘　　要：以某工程为例,采用岩石流变学中广泛应用的开尔文模型和广义开尔文模型对隧道围岩变形数据进行了回归分析和预测。结果表明,开尔文模型拟合精度较差,而广义开尔文模型与实测数据较为吻合,误差较小,能够更加准确的反映隧道围岩变形量与时间之间的关系,这对于准确预测围岩变形量和确定二次衬砌的时间具有一定的参考价值。Taking the engineering as an example, the article carries out regressive analysis and prediction of tunnel surrounding rock deformation data by applying Kelvin mode/widely used in rock rheological theory and broad-sense Kelvin model. Results show that the simulation accuracy of Kelvin model is rather worse. While the broad-sense Kelvin model is in accordance with actual surveying dada with little error. In addition, the surveying data can rather accurately reflects the relationship between tunnel rock deformation and time, which has certain referring value for accu- rately predicting surrounding rock deformation and for determining secondary lining time.
