Rockfall is a common mountain geological disaster. It has the characteristics of high release energy, sudden and strong disasters. In order to effectively prevent the occurrence of geological disasters such as rockfall. This paper takes the perilous rock mass of Baiyan Mountain in Guilin as the research object. The perilous rock mass of Baiyan Mountain is classified and numbered and the corresponding stability evaluation standard is formulated for the Baiyan Mountain perilous rock mass group. Based on the limit equilibrium method, the stability calculation methods of various types of perilous rock masses are established and the stability calculation analysis is carried out. According to the calculation results, the protective measures for different types of dangerous rock masses are proposed. The perilous rock mass mainly includes three types of perilous rock mass: overhead-type, slope-type and isolated-type. According to the calculation results, five protective measures are formulated for different types of perilous rock masses: support protection, removal project, pour mortar, anchorage-wire rope (nets) bounding and grouting and anchorage-screen. The research results are of great significance for the formulation of protective measures for perilous rock mass-es, as they provide a good reference for the prevention and control of geological disasters in mountainous areas.
