A good engineering geological environment is the premise of engineering construction safety and security. The construction of transmission lines needs to take topography, stratigraphic lithology, engineering geological hazard, structural geology into consideration, but the survey personnel always judge the engineering geological environment roughly only based on individual subjective experience, personal professional level when selecting the transmission line route. We call this judgment process has a gray feature in the point of gray system, while the gray scale can be reduced by the calculation based on gray system, each factor play their role in the evaluation process in their respective weight, so the quantitative, clear results can be obtained. This paper constructs the index system of engineering geological factors of transmission line, using gray evaluation system, and with the help of AHP, the quantitative evaluation results are obtained, and provide a theoretical basis for geological environment evaluation of transmission line engineering. Finally, the geological evaluation is carried out by a real construction and realized the transformation of theory to tool.
