| Abstract: | After synthetically considering the rock＇s character, rock mass＇s strength and structure character,development degree of groundwater,abnormal zone interpreted by geophysical exploration,the classification of surrounding rocks in Nanmukeng tunnel are analyzed and evaluated by comprehensive evaluation method,which is based onBQ] value classification and combined with surrounding rock mass＇s qualitative character evaluation.The result of classification of surrounding rocks is the basis of design and construction of the tunnel. |
