摘要
本文以遥感资料为主要的信息源 ,对成昆铁路沙湾至泸沽段泥石流沟的数量、分布、发生、发展趋势与运动规律进行了判译分析 ,并根据若干因素划分了泥石流沟的严重等级及其对铁路的威胁程度等级。针对泥石流对铁路的威胁程度 ,结合地形、地质、水文条件等因素 ,提出了治理对策 ,为遥感技术在工程地质病害调查和治理方面积累了经验。
This paper,by utilizing remote sensing as the main monitoring means and using the image interpretation and analysis,the quantity,distribution,feature,occurrence,trend of development,and regular movement of the mud rock flow are studied.Depending on several factors,the seriousness grade of mud rock flow valley and the menace level are classified.Finally,a series of control measures are put forward,according to the menace level of mud rock flow to the railway and other factors,for example,topographical features,geological features,and hydrologic phenomenoa.A wealth of experience about how to make use of remote sensing technology in surveying and harnessing railway disasters is also accumulated.
