隧道塌方预警预报体系研究

Research on Early Warning and Forecasting System of Tunnel collapse

本文通过对大量监测数据的分析,结合现有的隧道塌方监测和预警方面的国内外成果,将隧道塌方破坏前围岩变形的发展分为匀速变形、平稳发展、加速突变和破坏四个阶段,并根据四个阶段的变形特征,制定了隧道塌方预警预报的建议标准。

Based on the analysis of monitoring data and the existing case studies, four stages of tunnel collapse are suggested, which are uniform deformation phase, stable development phase, accelerated phase and destruction mutation phase. And in accordance with the characteristics of the four stages, the paper sets a recommended standard for tunnel collapse early waming and forecasting.
