REVIEW ON THE EVALUATION METHODS OF GEOLOGICAL HAZARD SUSCEPTIBILITY

The topographical and geological conditions in China are complicated, with frequent geological disasters, which have been aggravated by various human engineering geological activities. The prevention and management of geological disasters are the premise and foundation of ensuring the safety of people's lives and property. Geological disaster susceptibility evaluation is the premise of hazard evaluation and risk assessment, and the basis of geohazard zoning and prevention as well. Based on related researches on geological disaster susceptibility at home and abroad, the paper discusses the concept of geohazard susceptibility, evaluation index system, weight calculation method and evaluation model, and points out the main problems to be solved in geohazard susceptibility evaluation.
