Slope Stability Assessment Based on Fuzzy Matter-Element Extension Model

Article Preview

Abstract:

The slope stability assessment is performed to assess the safe and mitigation design of slopes and the equilibrium conditions. This paper selected Duke River located in Rangtang County, Sichuan Province, Western China as study area to delimit the areas liable to slope failure hazards. The fuzzy matter-element extension theory was used to analyze the slope stability of the study area. Six factors including slope, slope type, lithology, rainfall, elevation difference and land use were selected and classfied for assessing the slope stability. Result indicated that the unstable region was 1186 km2, which occupies 69.32% of the total study area. 16 slope failure hazards and 29 debris flow gullies sited through field investigation were used to test the assessing results. And the testing data indicated that the assessing result of the study area was reasonable.
