摘　　要：进行线路廊道滑坡地质灾害危险性评价与监测预警对线路的通畅和安全运行至关重要。本文以某铁路段廊道作为研究区域,结合地形地貌、地质、遥感信息、土壤、植被、水文及气候等数据,分析区段内滑坡孕灾影响因素并进行多因素方差分析,构建廊道滑坡稳定性指数地理空间信息模型,以此为基础对线路廊道进行滑坡危险性评估。针对诱发滑坡主要因素降水量的影响,对线路廊道滑坡危险性进行不同降水量条件下的分段评价,为铁路线路滑坡灾害评估、监测与预警工作提供理论与方法支持。Risk assessment,monitoring and early warning of landslide geological hazards is very important for railway safely operation along railway corridor.This paper takes a railway corridor as the research area,combines topology,geology,remote sensing information,soil,vegetation,hydrology,climate and other data,analyzes the impact factors of landslide disaster in the section,and carries out multi-factor variance analysis,and constructs the geospatial information model of the corridor landslide stability index,which is used as the basis for landslide risk assessment of the railway corridor.In view of the impact of precipitation,the main factor inducing landslide,the risk of landslide along the railway corridor is evaluated in sections under different precipitation conditions,providing theoretical and methodological support for the evaluation,monitoring and early warning of landslide disasters along the railway line.
