巷道顶板移动变形的动态数据处理

本文从布设巷道断面动态监测网出发,应用动态平差理论,分析了动态网形的时域可靠性,并应用突变论方法分析了测点位移系统的结构稳定性,提出了分区段分析建模原则,探讨应用门限自回归建模方法,实例验证了以上方法的正确性。

THE DYNAMIC DATA PROCESSING OF THE MOVEMENT AND DEFORMATION OF TUNNEL ROOF

This paper firstly establishes a dynamic control network for the tunnel section, and then analyzes the reliability of time period for the dyn amic network and proposes an effective method to determine the deformation of tunnel roof by means of the dynamic adjustment theory. To apply the catastrophe theory,the paper analyzes the structural stability for the displ acement system, the paper proposes the method to establish model by dividing all dynamic data into segments and simply introduces the application of the threshold autoregressive model on the deformation of tunnel root, examples demonstrate that the method is practical.
