新奥法隧道监控量测数据的回归分析及应用

摘要

以四川某隧道监控量测为例,应用Origin软件建立多种回归模型,通过回归系数选择合适模型,对实际数据进行处理与拟合,以此对隧道变形进行预测,判断开挖及支护方式是否合理,并选择合适的二次衬砌施作时机.%This paper takes a tunnel monitoring measurement in Sichuan as an example, used Origin software to establish a variety of regression models, through the regression coefficient to select the approximate model that can progress and fit the real data. As a result, we can predict the tunnel deformation and judge the excavation and support method whether is reasonable. Also, it can help to select the appropriate secondary lining for timing.
