Abstract: Aiming at the problem that the prevention and control strategy of the geological disaster of the traditional highway slope is not suitable for the protection of the mountain highway disaster, the formation mechanism of the geological disaster of the roadbed and slope of the mountain highway is studied, and the prevention and control strategy is put forward. The formation mechanism of collapse, landslide and debris flow disaster in mountainous area is analyzed. Based on the analysis results, the identification method of geological hazards is designed, and the corresponding prevention and control methods are put forward. The geological hazard identification method is used to identify the slope hazards that may occur in different mountainous areas, and the corresponding methods are used to form the prevention and control countermeasures of highway slope hazards in mountainous areas. Through the example verification, it is proved that compared with the traditional geological disaster prevention and control strategy, the proposed prevention and control strategy is more targeted, and the disaster prevention and control effect is better.
