基于AHP的模糊综合评判在公路地质灾害的危险性评价
|
摘要
以自贡市省道S305线一级公路地质灾害为研究对象,分析了公路复杂的地质环境条件—地质构造特征、地形地貌特征、水文气象特征地层岩性、断裂与地震等因素。采用改进的层次分析法,建构省道S305线一级公路的各类地质灾害评判模型,再结合经济损失,运用模糊综合评价数学模型,得出其地质灾害的危险性分区结论,为公路地质灾害的防治提供了科学的参考依据。
Geologic hazards are happening with increasing frequency along the provincial highway S305 within the boundaries of Zigong City.This paper establishes a geological hazards assessment model for the provincial highway S305 by use of improved hierarchical analytical method based on geological conditions such as geological structure,landform,topography,fault,lithologic character and so on,providing scientific basis for the geological hazard prevention and cure along the highway.
