摘要
利用层次分析法,建立成对比较矩阵,将成对比较矩阵的特征向量作为典型滑坡评价因子的权重,确定了评价因子的影响力排序。建立了滑坡危险度评价指标,并确定了滑坡危险度等级,为滑坡预警和滑坡的治理提供了依据。
Based on analytical hierarchy process(AHP),this paper established the pairing comparison matrix. Taking characteristic vectors of the pairing comparison matrices as the weights of assessmaent factors for typical landslide, the influence order of the assessment factors was determined. Assessment indices of hazard degree for landslide are set up and the grade of landslide hazard degree was defined. They provide a basis for warning and control of landslide.
