Abstract:
Based on the monitoring measured data and combined with grey theory, tunnel hole body displacement deformation system was established. The analysis was made on the stability of temporary supporting structure for excavation with cusp catastrophe method to build prediction model of tunnel collapse. The practical case of collapsing accident in Dujiashan tunnel showed the same result with that of prediction.
