基于回归分析的隧道收敛预测

Tunnel convergence prediction based on regression analysis

隧道工程地质条件复杂,变形监测精度要求较高,收敛值是主要的监测指标之一。随着时间的增加,收敛值呈现出规律性的变化,可用于掌握隧道的安全状态。以实测收敛值为例,使用回归分析方法分析收敛值与时间之间的关系,同时,对收敛值进行预测。分析结果表明,隧道的收敛值与时间之间存在非线性关系,收敛值预测准确。

The geological conditions of tunnel engineering were complex,so it required high accuracy in deformation monitoring,and the convergence value was one of the main monitoring indicators. With the increase of time,the convergence value shows a regular change,which can be used to grasp the safety state of tunnels. Taking the measured convergence value as an example,this paper uses regression analysis method to analyze the relationship between convergence value and time. At the same time,the convergence value was predicted. The analysis results show that there is a nonlinear relationship between the convergence value of the tunnel and the time,and the convergence value was predicted accurately.
