Abstract The evaluation of geological environment suitability is an important part of the location selection of the power transmission and transformation engineering. According to the characteristics of the geological environment factors affecting the construction and safe operation of the power transmission and transformation engineering in Suyu area, the authors chose 8 factors as evaluation indicators, including bearing capacity, liquefaction index, seismic structure, ground motion peak acceleration, ground elevation, terrain slope, river system and road network density, and the weight of each factor is determined by the method of analytic hierarchy process (AHP). On this basis, the suitability classification map of the transmission line project in the Suyu area is obtained, using the multi-factor spatial fitting function of GIS. The results show that the Suyu area is basically belonging to suitable and relatively suitable zones for power transmission and transformation engineering, except for Luoma Lake system. While the areas around Tan-Lu fault zone belong to poor suitable zones, affecting by the fracturing structure, which needed to be avoided.

Key words： AHP multisource information fusion power transmission line engineering geological environment
