    ASSESSMENT METHOD FOR GEOLOGICAL CONDITIONS OF SURROUNDING ROCKS ALONG HIGHWAY TUNNELS AND ITS APPLICATION TO FUXI TUNNELING

    • 摘要: 为了达到快速、准确、可靠的围岩分类,有效指导隧道施工,在充分研究和吸取国内外有关围岩分类的经验和成果基础上,针对隧道施工期间的围岩类别鉴定方法,提出了一种可用于隧道施工期间围岩类别鉴定的快速分类方法,该方法以定量与定性相结合、多专家评分的方式在开挖掌子面现场进行观察、量测及评价,无需复杂试验或测量以及繁杂计算,可迅速得出评价结果。为了更加全面地反映隧道围岩情况,准确评价围岩工程性质,结合目前国际上流行的Q分类系统,在富溪隧道第一手实测资料的基础上,根据快速分类结果和Q指标分类结果对富溪隧道围岩条件进行综合评价,为其隧道施工提供了合理的支护参数。

       

      Abstract: In order to quickly and accurately classify surrounding rock and instruct the tunnel construction, and on the basis of comprehensive review of the surrounding rock classification methods in domestic and abord, the paper proposes a method for quickly classification of surrounding rocks during tunnel construction period. The method combines qualitative and quantitative evaluations and uses experts evaluation method to quickly obtain the appraisal result for observing, measuring and appraisaling the surrounding rocks in the scene of excavating tunnel face. It does not need complex experiments and computations. In order to comprehensively reflect the tunnel surrounding situation and accurately appraise the project nature, and take into consideration of the Q-system, the paper appraises the surrounding rock of Fuxi tunnel on the basis of the first hand survey data using both the quick classification method and the Q-system method. It provides the rational supporting parameters for the construction of Fuxi tunnel.
