Evaluation method of engineering construction stability for expressway tunnels based on dynamic classification of wall rock
-
摘要: 針對高速公路隧道工程施工的特點,基于動態化的圍巖分類,采用多種方法對隧道圍巖進行地質跟蹤調查與預測.通過綜合分析和優化處理上述信息,從而對公路隧道動態穩定性進行評價,為高速路隧道工程穩定狀況的評判提供了一種簡單易行的方法.Abstract: According to the engineering construction characteristic of freeway tunnels, some methods were adopted to investigate and predict the geological condition of tunnel wall rock on the basis of dynamic wall rock classification. The information obtained by these methods was integratively analyzed and optimized so as to evaluate the dynamic stability of expressway tunnels. The results of practical application show that this evaluation method is simple and effective.
