ABSTRACT
The southwest of China is karst region and in this kind of region, the geotechnical stratum's structure is very complex, so it is very difficult to build the tunnel in the region, as the engineering experience in such long-distance karst is lack. The author introduced fuzzy theory and grey fuzzy theory respectively, list the impact factors of the negative effects of groundwater environment in tunnel project to make subordinate fuzzy function. The objective of this study is to ensure whether the risk in tunnel construction in karst can be evaluated and reduced by using grey fuzzy method. Based on MATLAB Software Platform, the grey fuzzy comprehensive evaluation of tunneling engineering has been realized by combination of fuzzy theory, Analytic Hierarchy Process (AHP) method and the gray correlation analysis method relying on the tunneling of Dian-Ling highway in TongLuo Mountain. The conclusion shows that the preliminary comprehensive evaluation is scientific and efficient in the application for tunneling engineering and grey fuzzy method is more reliable than fuzzy method in karst field.
