Fuzzy Comprehensive Evaluation Method and Its Application in Judging the Risk Degree of Debris Flows
Xiao Sheng-xie · Journal of Chongqing Jiaotong University · 2008
Aiming at the analysis of the debris flow disaster characteristics,the evaluated factors and the nonlinear subordinate functions are selected to determine the membership degree of every factor.The weights of the impacted factors are determined by the hierarchy process.The dangerous size of the mudslides is assessed by the secondary fuzzy analytic method.And the example assessed by the dangerous size of the five debris flow ditches in Yunnan show that the fuzzy analytic method can reflect the dangerous conditions of the debris flow,and it provides the decision-making basis for the debris flow prevention and the project reinforcement.
