The Application of Grey Matter Element Analysis in the Geological Hazard Risk Evaluation

The geological conditions in our country are complex, the geological environment is fragile, and the types of geological hazards are diverse, which has brought severe economic losses and casualties, and becomes an outstanding problem in the development of our society. In this paper, according to the common features of geological hazards, the risk evaluation system of geological hazards is constructed. The grey matter element analysis and grey theory are used to establish the risk evaluation model of geological hazards. The geological hazard risks are divided into 4 grey clustering. This method provides a professional, scientific and reasonable evaluation method for the geological hazard risks.
