Risk Evaluation of Debris Flow Based on Fuzzy Comprehensive Evaluation and Entropy Method
DU Guo-lian · Safety and Environmental Engineering · 2013
Debris flow risk assessment is an important research direction in geological engineering field at home and abroad in current years,and it is also important and difficult in the study of debris flow.This paper establishes a model based on fuzzy comprehensive evaluation and entropy method and chooses 8evaluation factors,such as the basin area,the length of the main gully,the relatively maximum elevation difference in the basin,the longitudinal slope of the main gully,the maximum volume of debris flow and so on,to evaluate the risks of 8debris flow gullies in Min County.The results show that evaluation results are consistent with the actual situation and the method is rational and valid in the risk evaluation of debris flow.
