山区沿河公路崩滑灾害危险性评价方法及应用——以横断山区美姑河流域公路崩滑灾害为例
Collapse and Landslide Hazard Evaluation of Mountainous Highway along River——Taking collapse and landslide hazard along Meigu river highway in Hengduan Mountains as an example
摘要
Abstract
To support landslide-collapse mitigation decision of mountainous highway along river,and according to developing characteristic of the landslide-collapse,hazard for landslide-collapse of mountainous highway along river is comprehensively evaluated from disaster-breeding environment and disaster-inducing factors.Using GIS and remote sensing image interpretation,landslide-collapse disaster inventory and disaster factors database are established,and assessing indexes are selected simaltaneously.The weight for each index is calculated based on historical landslide-collapse area distribution information entropy.The landslide-collapse hazard evaluation method is established after quantitative statistics of landslide-collapse index.The method is applied to the hazard evaluation for landslide-collapse along Meigu River.The comparison between results of this method and the actual disaster situation of research area shows that the present method has certain reliability.The hazard evaluation result can provide the reference for landslide-collapse mitigation decision-making of mountainous riverbank highway.关键词
