Abstract

It is of great practical value to study the risk assessment of debris flow in the earthquake zone for ensuring people's safety and constructing key projects. Taking six debris flows in the earthquake area as examples, this paper calculates the weight of each Impact factor by using the analytic hierarchy process (namely subjective weighting method) and gray relational degree method (namely objective weighting method), then the weights of subjective and objective are calculated and dealt with using combination weighting, and the highest proportion of weight are annual rainfall and seismic intensity respectively.
