京九铁路地质调查中遥感技术的应用

Application of Remote Sensing Technology in Geologic Survey of Beijing-Kowloon Railway

为配合京九铁路预可研、初定测及重点工程的施工工作,遥感技术开展了广泛的航卫片解译工作。本文介绍了遥感解译、分析的主要成果:大别山区古老变质片岩岩性、黄梅—小池口段软土分布、坪埔—大池段岩溶地段和河源大断裂带的选线、构造复杂的孟良山隧道的综合勘探以及岐岭隧道问题的处理等,为线路勘设提供了重要资料。在此基础上探索遥感技术如何在综合勘探中发挥更大的作用以及长大干线勘察中遥感的作业程序。

In order to coordinate the pre-feasibility study,initial and defined investigation and the construction of major project,the geological interpretation of aerial and satellite photograph has been taken in remote sensing technology. This paper introduces the main achievements of remote sensing interpretation and analysis:the lithology of ancient metamorphic schist in Dabieshan area,the distribution of soft soil in Huangmei-Xiaochikou area,the route selection in Pingpu-Dachi karst area and great fracture area in Heyuan,the comprehensive exploration in Mengliangshan Tunnel with difficult structure and the settlement of Qiling Tunnel's problems and so on.These mentioned above provided important information for railway's exploration and design.On this base,we need to explorate remote sensing technology how to play more important role in comprehensive prospecting and the procedures in main line exploration.
