| 摘 要： | 基于50多条两车道NATM高速公路隧道的现场监测数据，通过对围岩收敛变形和拱顶下沉数据的统计分析，探讨隧道II，III，IV，V级围岩随时间的变形特性，得到不同级别围岩隧道从开挖到变形稳定的时间，分析稳定时间与围岩级别的关系，为隧道施工阶段围岩的稳定性评价以及二次衬砌的合理施做时机提供依据。

| Abstract: | Based on field monitoring data of more than fifty two-lane highway tunnels，the data of convergence displacements and vault settlements were analyzed through statistical method. The deformation characteristics of different surrounding rock levels from II to V with time were also studied，and the stable time was proposed for surrounding rock from excavation to stabilization. The relationship between levels and stable time of surrounding rock was defined，which provided basis for evaluation of surrounding rock and construction time of secondary lining. |
