Taking a transmission line in Ganzi Prefecture, Sichuan Province as the research object, based on the detailed survey data of geological hazards collected, the distribution rules of geological hazards along the transmission line were studied through high-precision remote interpretation and field investigation verification. Main results of this paper can be concluded as follows. (1) The results show that there are 89 collapses, 113 landslides, 235 debris flows and 6 unstable slopes along the transmission line, and the geological hazards are distributed in a zonal pattern. (2) The soft clastic rock group is the most widely distributed and has the largest number of collapses and landslides, while the hard clastic rock group has the largest density of geological hazards. (3) The collapse and landslide mainly distributed in the elevation range of 3100m~3700m. (4) The collapse and landslide mainly distributed in the slope range of 10°~40°. (5) The control distance of the fault on the collapse and landslide is 2500m and 1500m, respectively. (6) The control distance of water system and road construction on the collapse and landslide is 600m and 900m, respectively. (7) Fitting the relation of collapse and landslide to fault, water system and road, the practice shows that the fitting effect was perfect by using polynomials and exponential function.
