With the example of rockfall geological hazard in Beijing Baiquanshan scenic spot, this paper systematically introduces the hazard about the dangerous rock belt (mass) scale, dangerous rock characteristics, damage mode and damage degree, etc., and according to the geological hazard characteristics, development degree and the traffic conditions in the valleys, the analysis, comparison and selection are made on variety of treatment schemes, the final choice are cutting down earth on the upper anti-dip part of the dangerous zone to remove the dangerous rock mass, float stones on steep slope and loose rock mass and hanging active protection net.
