摘要
本文从布设巷道断面动态监测网出发,应用动态平差理论,分析了动态网型的时域可靠性,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,探讨了应用门限自回归建模方法,实例验证了方法的正确性。
Starting from the setting up of the dynamic montoring network of tunnel section , applying the dynamic adjustment theory. this paper analyzes the time ?domain reliability of the dynamic network type. Also . applying the method of mutation theory . it analyzes the structural stability of the displacement system of the surveying points . proposes the model establishing principle of analysis in segments, and discusses the model establishment by applying the threshold autoregression method . By case history t the correctness of the method is verified .
