基于GIS和信息量模型的京张高铁滑坡易发性评价
LANDSLIDE SUSCEPTIBILITY ASSESSMENT OF NEW JING-ZHANG HIGH-SPEED RAILWAY BASED ON GIS AND INFORMATION VALUE MODEL
摘要
Abstract
New Jing-Zhang high-speed railway is not only an important supporting transportation infrastructure for the 2022 winter Olympics in Beijing,but also an important part of the eastern section of the "eight vertical and eight horizontal" Jinglan corridor that the state plans to implement.Based on the investigation of the landslide disaster along the Jing-Zhang high-speed railway,a statistical analysis on the correlation factors affecting the development of geological disasters are made in this article.A total of 10 variables are analyzed as input variables,namely topography (height,slope and aspect),vegetation coverage ratio,engineering rock group,fault,river,rainfall,earthquake and human activity of the study area.The results of landslide susceptibility assessment based on GIS and information value model of New Jing-Zhang High-speed Rail will be divided into 5 grades:extremely high susceptible,high susceptible,moderate susceptible,low susceptible and extremely low susceptible.The results of the model preferably inosculate with the field surveying,and the results of this article can provide a valid basis for the railway construction in the future.关键词
