摘要
《JTG D70-2004公路隧道设计规范》中定性与定量[BQ]值相结合的两步分级法从定性和定量两个角度出发,互相校验和检验,采用多因素指标进行评判,对影响围岩稳定性的分析较为全面,该方法在安徽六潜高速公路隧道中应用效果较好,为调整优化相应工程措施提供了重要依据。
Two - step Classification Method in the Code for the Design of Road Tunnels (JTG D70 -2004) classifies the surrounding rocks on the qualitative and quantitative bases and they can verify each other. With multi - factors considered, the method is comprehensive to identify the stability of surrounding rocks. It was applied in Li- uqian highway tunnel in Anhui province which provided the important basis for the adjustment and optimization of the corresponding engineering measures.
