贵州省规划铁路网滑坡危险性评估
Landslide risk assessment for planning railway network in Guizhou Province
摘要
Abstract
Based on medium and long-term railway network plan and a landslide susceptibility map which was derived from logistic regression model, three factors, namely the landslide susceptibility index, the influence degree of historical landslide events around to a railway line, as well as design speed were proposed and quantified for a GIS-based landslide risk assessment for regional planning railway network. Based on the extenics theory, the landslide risk of railway was divided into four levels, and a matter-element model was built to assess the risk level for the total 17 sections of railway. The results show that in Guizhou Province, four sections of railway such as Chengdu-Guiyang railway are at very high risk, four sections such as Changsha-Kunming railway are at high risk, five sections such as Guizhou-Guangzhou are at medium risk and four sections such as Tongren-Yuping are at low risk. The assessment result provides references for railway planning, construction and maintenance in Guizhou Province.关键词
