BQ法和灰色关联法相结合的隧道围岩分级验证研究

Study of the surrounding rock classification of highway tunnel by means of the combination of BQ Method and grey relational analysis through comparative analysis

公路隧道围岩分级一直是研究人员共同关注的重要课题。分析了公路隧道分级方法存在的问题,然后通过对比分析,提出了以BQ法和灰色关联分析法相结合的公路隧道围岩分级方法。通过对杭州至瑞丽国家高速公路大兴段与思南段的太平河1号隧道的应用研究,此方案取得了很好的应用效果,给施工单位提供了有效科学的指导。

The rapid development of highway tunnel brings new challenges to the advance of Tunneling. The surrounding rock classification is always a key project of common concern from the researchers. This thesis analyzes the problems existing in the classification of highway tunnel at first, and then puts forward the surrounding rock classification of highway tunnel by means of the combination of Method BQ and grey relational analysis through comparative analysis. By the applied researches of Guizhou Tai pinghe 1 tunnel of Hang Rui high-speed this method has achieved satisfactory results of application and provides effective scientific guidance to constructors.
