Landslide Risk Evaluation Based on Analytic Hierarchy Process Method and Fuzzy Comprehensive Evaluation

Excerpt

Landslide risk evaluation is influenced by several factors with fuzzy and uncertain characters. At present, most landslide risk evaluation projects mainly use the qualitative experts marking law having certain subjectivity to the results. With regard to the above considerations, based on the analysis of some influencing factors on landslide development, the weight vectors of these factors are quantified by using analytic hierarchy process model, then are introduced into fuzzy comprehensive evaluation. A mathematical model based on analytic hierarchy process and fuzzy comprehensive evaluation is established for landslide risk evaluation. According to these discussions, through evaluating the Green Grass Back NO.1 landslide risk in Wan Zhou district, and comparing the final results with those achieved from the traditional stability calculation method in three kinds of work conditions, and the paper verifies that the application of the model in landslide risk evaluation is legitimate and credible. Project application result indicates that the method reduces the cost, and the disadvantages of personal subjective judgment are avoided, so it's believed that the method researched in the paper has important project practical value.
