| 中文摘要:利用监控量测数据，结合灰色理论建立隧道洞身位移变形系统。采用尖点突变分析方法,对开挖过程中初支结构的稳定性进行分析,建立隧道塌方预测模型。通过杜家山隧道发生的塌方事故与预测模型进行验证，得出塌方预测结果与实际情况相吻合；说明建立的隧道塌方预测模型是有效的,可以用来指导该类隧道的施工。 |

| 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. |
