基于信息量-Scoops3D联合模型的地质灾害易发性评价
Evaluation of the Susceptibility to Geological Hazards Based on the Information-Scoops3D Joint Model
摘要
Abstract
The terrain along the Guizhou-Chongqing Pipeline is rugged,the geological structure is ac-tive,and the rainfall is concentrated,leading to the development of geological hazards such as land-slides and debris flows..Scientific assessment of the susceptibility to geological hazards along the pipe-line is crucial for ensuring operational safety.Based on the investigation of the natural geological envi-ronment and disaster distribution along the pipeline,this study divided the pipeline route into 101 eval-uation units.These units were determined by considering the terrain,geological characteristics,spa-tial relationship between the pipeline and the slopes.The susceptibility to geological hazards along the pipeline was evaluated using an information value statistical model and the Scoops3D physical mechan-ics model.The results indicated high-risk areas of geological disasters were concentrated in the vicinity of Zunyi and Tongzi counties.Among the evaluated sections,7 were in extremely high-risk areas,26 in high-risk areas,20 in medium-risk areas,30 in low-risk areas,and 18 in the very low-risk areas.The AUC values of the information model,the Scoops3D model and their combined model,deter-mined using ROC curves,were 0.796,0.683 and 0.803,respectively,indicating that the information-Scoops3D joint model had the highest evaluation accuracy.关键词
