南昆铁路施工阶段遥感工程地质调查的应用

Application of Remote Sensing Technology in Engineering Geological Survey of Nanning-Kunming Railway Construction

本文根据以往铁路施工过程中暴露的地质问题,提出在施工阶段应用遥感技术进行地质调查的必要性,认为施工阶段应用遥感技术可发挥较好的作用,并以南昆铁路为实例,叙述了施工阶段应用遥感进行地质调查的可行性和优越性。在南昆铁路施工中共进行了15个工点(地段)的遥感工程地质判释,提供的成果经施工验证,绝大部分是正确的。最后认为在某些情况下,有针对性地开展遥感地质判释是可行的,并指出施工阶段应用遥感技术是一次突破性进展,它拓宽了遥感地质应用范围,具有广阔的应用前景,但有些问题也仍待摸索和总结提高。

According to the exposed geological problems in previous engineering construction,this paper puts forward the necessity of making geological investigation and points out that it may exploit quite nice role in construction stage to use remote sensing technology.Take the Nanning-Kunming Railway for example,this paper also expounds feasibility and advantages of applying remote sensing technology to make geological investigation.There are 15 spots (sections) carried out the remote sensing interpretation in construction of the Nanning-Kunming Railway and most of the achievements obtained form construction have been proved to be right.Finally,in some cases,it is feasible to make remote sensing geological interpretation againt specific conditions.And it points out that it is a breaking development to apply remote sensing technology in construction stage.It makes extension of applicable scope of remote sensing geology and has enormous prospect, But there are still some problems to be found and concluded.
