| Abstract: | 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 Liuqian highway tunnel in Anhui province which provided the important basis for the adjustment and optimization of the corresponding engineering measures. |
