基于D-InSAR的中老铁路景洪段沿线地表形变统计分析
A Statistical Analysis of Surface Deformation along the China-Laos Railway Jinghong Section Based on D-InSAR
摘要
Abstract
Taking the Jinghong section of the China-Laos Railway,which is prone to geological disas-ters,as the research object,the differential synthetic aperture radar interferometry(D-InSAR)technol-ogy was used to statistically analyze the surface deformation in the area within 1 km around the Jing-hong section.The results show that:(1)The deformation rate along the Jinghong section of the China-Laos Railway ranges from-146.247 to 159.529 mm/a,with more subsidence in the north and more uplift in the south,and the subsidence in some local areas is relatively obvious;(2)The influencing factors of key deformation areas along the Jinghong section of the China-Laos Railway include alti-tude,engineering geological rock groups,vegetation coverage,etc.The deformation in mountainous ar-eas along the railway is mainly concentrated at 900～1 300 m,with a gradient of 5°～25° accounting for 86％.The lithology of the deformation area is mostly soft rock.关键词
