摘    要:以往铁路遥感技术是用于勘测阶段 ,本文扼要地叙述了遥感技术在南昆铁路施工地质调查中应用的概况及效果 ,这是遥感技术首次用于施工的一次尝试 ,也是遥感技术应用的一个突破。文中首先对沿线地形、地质概况进行介绍 ,然后结合施工部门的要求 ,开展全线陆地卫星 TM图像的断裂构造判释 ;利用全黑白像片开展主要隧道、部分地段岩溶、八渡桥位地区等的判释 ;利用不同时期航片对段家河流域的泥石流沟进行动态分析。文中还列出该线部分地段地质遥感图像判释意见与施工验证结果对比一览表。从该表得知遥感判释成果绝大部分是对的。最后 ,在结论中归纳出几点认识 ,并提出施工阶段在特定条件下有针对性地应用遥感技术是有益的。同时指出 ,施工阶段应用遥感技术是有条件的 ,并非任何情况下均可应用遥感技术。

关 键 词:遥感地质调查  南昆铁路

Abstract:This paper outlines the process and effciency of applying remote sensing technique in the geological survey during construction of Nanning-Kunming Railway. Because the remote sensing was only used in the surveying period in the past time, this practice is the first time for applying remote sensing during construction,and therefore is a break-through of the usage of remote sensing. The paper describes firstly the geomorphology and the sketch of geology along the railway. According to the requirements of the construction authority,the interpretation of fault-related structures were carried on the whole railway by using the Landsat TM images. White-black images were used for the geological interpretation of main tunnels, karst areas and the locality of Badu Bridge. Aerial photos taken in different times were applied to dynamic analysis of mud-rock flow valleys in the Duanjia River drainage area. The paper also lists the comparisons between the suggestions of remote sensing interpretation and the testifying results of construction in some segments of the railway. It can be seen from the list that most results of the remote sensing interpretation are correct. Finally, this paper deduces some conclusions and puts forward that it is beneficial to apply objectively and considerately the remote sensing technique in the construction. Meanwhile, the paper points out that the application of remote sensing technique do not mean mag be appied anywhere.
Keywords:remote sensing geological investigation  Nan-Kun Railway
