多元线性回归分析在引水洞变形预报中的应用

Application of Multiple Linear Regression Analysis in the Prediction of Water Diversion Tunnel Deformation

在引水洞的开挖施工过程中,会使地表产生一定的变形,同时岩土压力也会对引水洞造成不同程度的变形,使施工安全存在一定隐患。该文以深圳抽水蓄能电站引水隧洞为例,用多元线性回归分析对该建筑物的监测数据进行分析预报,其预报结果与后期实测数据进行对比,分析残差精度较为理想,证明该方法可行。

In the production a certain deformation tunnel,will produce a certain deformation. Rock and soil pressure will cause different degree of deformation to water diversion tunnel,produces certain hidden danger of construction safety. This paper takes Shenzhen Pumped Storage Power Station as an example,using multiple linear regression analysis to the building monitoring data analysis and prediction,prediction results with the actual data for comparative analysis,residual meet the accuracy requirements.
