Assessment of Landslide Hazard in the Middle and Northern Xiaojiang Fault Zone Based on GIS
摘要
Abstract
The middle and northern Xiaojiang fault zone is the most important active structure in the reservoir area of the major hydropower project in the lower reach of the Jinsha River,where the geological effects of landslides along have seriously restricted the local economic and social development. Based on detailed investigations of the landslides along the fault,nine influencing factors including slope,slope direction,geotechnical rock group,bank structure and fault structure are selected as the evaluation indexes to study the distribution of potential landslides in the study area. A risk assessment mod-el of landslide hazard is established by the AHP-CF method, and the risk areas are delineated by using GIS spatial analysis function. The test curves show that the AUC value is 80%.关键词
