层次分析法在区域地质灾害危险性评估中的应用——以夏甸风电场为例

Application of Regional Geological Hazards Assessment by Using Analytic Hierarchy Process—Setting Xiadian Wind Farm as an Example

摘要:

将该项目区域视为一个小型区域，以此作为一个区域模型，并分为38个评估单元，结合野外调查数据及地质分析法进行评估，针对风电场区域大，地质环境条件多变，考虑了多个影响因素的综合作用，运用基于层次分析法对风电场区域地质环境、地质灾害进行综合评估。将38个单元逐个进行计算后，划分出了危险性中等区和危险性小区，层次分析法的评估结论与地质分析法的结论基本一致，层次分析法确定的危险性中等区涵盖地质分析法确定的危险性中等区。推广到类似区域进行合理、定量地划定区域危险性等级，给城市新区建设选址提供参考依据。

Abstract:

Regarding the project area as a small area and a regional model, 38 evaluation units have been divided. Combining with field survey data and geology analysis method, pointing to large wind farm area and variable geological environment condition, considering comprehensive effect of multiple factors, and using hierarchical analysis method, regional geological environment and geological disasters of the wind electric field have been evaluated comprehensively. After calculating 38 units one by one, medium risk areas and small risk areas have been divided. AHP assessment conclusions and geological analysis conclusions are basically the same. Medium risk areas determined by using hierarchical analysis cover dangerous areas determined by geological analysis method. It will provide some references for rational and quantitative division of regional risk level, and the construction of urban new districts.
