川藏铁路(成都-雅安段)线域滑坡地质灾害时间-空间敏感性分析
Landslide spatiotemporal susceptibility analysis of Chengdu-Yaan section in Sichuan-Tibet railway
摘要
Abstract
Landslide spatiotemporal susceptibility mapping model was established by combining landslide spatial mapping method, which is based on subjective and objective integrated weighting model, with landslide temporal mapping method based on effective rainfall model. The landslide spatiotemporal susceptibility map of Sichuan Province was obtained using this model. By coupling Chengdu-Yaan section in Sichuan-Tibet railway, the landslide spatiotemporal susceptibility grade of this railway line was acquired. The results show that the coverage area of high susceptible zone in Sichuan Province is 230 432.6 km2, accounting for 47.78% of the whole province area. These areas are mainly distributed in south, central, southeast and northeast land. The railway line of high susceptible zone is 23.26 km, occupying 58.66% of the total, distributing in K97+728.00~K120+992.61 section.关键词
