铁路工程地质遥感技术应用现状与展望

Application Situation and Prospect of Remote Sensing Technology for Railway Engineering Geology

在总结遥感源平台、三维遥感技术、雷达遥感技术等在铁路工程地质勘察中的应用现状基础上,探讨了铁路工程地质遥感工作需要进一步研究的内容。目前,三维遥感判释技术逐渐应用于铁路勘察工作中,但以定性判释为主,需要加强定量判释技术的开发和应用。干涉雷达遥感技术在监测区域沉降变形中具有明显优势,而成像雷达技术在铁路勘察中应用还很少。随着我国高铁运营里程的快速增长,既有线地质灾害遥感筛查工作应引起足够重视。同时,应加强国产卫星遥感数据在铁路行业的应用。

Based on the summarization of the application situation on remote sensing platforms,three-dimensional remote sensing and radar remote sensing technologies,we discussed the further research on remote sensing of railway engineering geology. At present,the three-dimensional remote sensing interpretation technology is gradually applied in the railway surveying,however,the development and application of quantitative interpretation technology should be strengthened. Interferometric synthetic aperture radar technology has obvious advantages in monitoring the land subsidence,but the application of imaging radar in railway survey is rare. With the rapid growth of China＇s high-speed railway,the geological hazard investigation of the existing line by remote sensing technology should be paid more attention,furthermore,the application of domestic remote sensing data should be strengthened in railway engineering.
