Fuzzy Comprehensive Analysis on the Slope Stability of Jinjiang Farmland Irrigation Canal

    Graphical Abstract
    • Abstract
  • PurposeTo study the stability of the slope along the Jinjiang farmland irrigation canal in Jinjiang Township, Lijiang Old Town.
    MethodOn the basis of detailed field investigation, based on the analytic hierarchy process and fuzzy comprehensive evaluation, four evaluation criteria and 14 low indicators including engineering geological characteristics, topography and geomorphology, meteorological and hydrogeological conditions, man-made and other external factors were constructed the evaluation model of slope stability of farmland irrigation canal.
    ResultThe safety risk grade score of the project after platform excavation was 75.834, which belonged to the basic stability risk level. After the construction platform was completed, the safety risk grade score under the irrigation channel excavation condition was 68.500, which belonged to the unstable risk level.
    ConclusionAccording to the analysis results, the corresponding suggestions and measures were put forward. The research results are of great significance to ensure the slope stability of Jinjiang irrigation canal and the optimization of water delivery scheme, which can provide reference for similar projects.
