基于层次分析法的高速公路地质灾害危险性评估——以十宜高速兴山至长阳段为例

Highway Geological Hazard Evaluation Based on Analytic Hierarchy Process—Taking Shiyi Highway Xingshan to Changyang Section Project as an Example

地质灾害危险性评估是高速公路项目建设前期一项重要工作。本文在详细研究高速公路沿线地质灾害发育类型及特征的基础上,采用层次分析法(AHP)构建了包含3个一级孕灾因子和9个二级孕灾因子的指标评价体系。根据权重分析及各评估区不同因子的赋值,并通过因子叠加运算,得出各评估区最终的评估分值及危险性等级。研究成果可为高速路规划和防灾减灾提供理论依据。

Geological hazard evaluation is an important work in the early stage of highway project construction. Based on a detailed study of the types and characteristics of geological hazards in the assessment area, this paper uses the analytic hierarchy process (AHP) to construct an index evaluation system that includes three primary factors and nine secondary factors. Based on the weight analysis and the assignment of different factors in each evaluation area, the final evaluation scores and danger levels are obtained through the factor superposition operation. The results can provide a theoretical basis for highway planning and disaster prevention and reduction.
