隧道监控量测数据分析与应用

Analysis and Application of the Data on Tunnel Monitoring Measurement

在隧道施工中,监控量测是隧道新奥法施工三大要素之一,通过量测及时收集施工中围岩变形与支护受力数据,对数据整理分析及时反馈指导施工。隧道施工监控量测因用途的不同有各种选项,拱顶沉降和周边位移是最常用的二项,文章以某隧道量测结果为例,主要论述拱顶沉降和周边位移量测数据通过回归分析建立数学模型,从而评价和预测围岩的稳定情况。

Monitoring measurement is one of the three main means that are used in New Austrian Tunneling Method, by which the data on wall rock deformation and load on enclosure can be acquired timely to guide the following construction. Monitoring measurement can be done on different subjects for different uses but commonly on vault settlement and perimeter displacement. The artide combines with a project to introduce as how to make regression analysis of the data on vault settlement and perimeter displacement and then establish mathematical model to evaluate and forecast whether or not the wall rock is stable.
