Evaluation of Seismic Landslide Runout Distance Based on the Fuzzy Mathematics and Range Analysis
The Runout Distance is One of the most Important Factors of Landslide Hazard. it Not only Controls the Hazard Area but also Influences on the Landslide Hazard Assessment. Based on the Data of Landslides Induced by the Wenchuan Earthquake, the Six Slope Structures, Including Rock and Soil Mass, Slope Type, Gradient (α), Slope Height ( h), Azimuth Difference between Slope-Aspect and Strata Trend(θ1), Difference between Slope Gradient and Obliquity of Rock Layer (θ2), and Seismic Intensity were Selected to Evaluate the Landslide Runout Distances. the Evaluation Model of Landslide Runout Distance was Proposed by the Combination of Fuzzy Mathematics and Range Analysis. the Results Indicated that it was Different that the Slope Structures Influenced on the Runout Distance in the Different Volume Scale. According to the Evaluation Model, the Typical Landslide Runout Distances were Studied, and the Evaluation Results Accord with the Actual Runout Distances.
