在公路隧道监控量测工作中,监测数据的整理和分析是非常重要的环节。对监测数据,除进行一般性的图示和分析,进行回归分析是行之有效的方法手段。公路隧道监控量测资料回归分析的思路是,采用对数、指数或双曲函数模型,并转化为一元线性数学问题,求得回归系数,在一定的置信度下求得数据的相关系数以选择合理的回归模型,根据回归模型和回归系数对量测数据进行分析和评价。以在建的山西岢临高速公路隧道监控量测为例,采用回归分析方法,对实际数据进行了处理分析和图示。
In the monitoring work of highway tunnel, the collation and analysis of monitoring data is very important. The monitoring data, in addition to the general illustrations and analysis, regression analysis is an effective method of means. Road tunnel monitoring measurement regression analysis of the idea is that the use of logarithmic, exponential or hyperbolic function model, and converted to a linear mathematical problem, the regression coefficient obtained with a certain degree of confidence to determine the correlation coefficient of the data to choose A reasonable regression model, based on regression models and regression coefficients of the measured data analysis and evaluation. Taking the monitoring of Shanxi Yinglin Expressway under construction as an example, regression analysis is used to analyze and display the actual data.
