| 摘 要： | 通过对回归模型在变形监测的应用研究,结合工程实例,对某高铁隧道的拱顶沉降值运用分段回归模型进行分析预测,建立时间和位移变形量的回归分析模型,并从统计检验、曲线线型、拟合度三个层面进行评价,得出分段回归模型可以较好的预测隧道断面的变形趋势,从而验证了该方法的工程实用价值。

| Abstract: | By applying the regression model in deformation monitoring,combined with engineering examples of a tunnel vault settlement value,segmented regression model analysis and forecasting,regression analysis model of deformation and displacement with time were made. The statistical test,the curvilinear and fitting were carried out to evaluate the results. Segmented regression model can better predict the deformation trend of tunnel section to verify the practical value of the method. |
