多源遥感技术在铁路工程地质勘察中的应用研究

Application Research of Multisource Remote Sensing Technology in Railway Geological Surveying

遥感技术已经成为铁路工程地质调查的一个重要手段,但是采用单一数据源及传统判释方法往往很难达到较好的调查效果,也满足不了不同勘察阶段地质调查的需求。为了提高铁路工程地质遥感调查的质量和效率,探讨多源遥感技术在铁路工程地质勘察中的应用,针对不同遥感影像数据建立不同的三维判释环境,以多片种、多尺度、多角度相结合的方法进行工程地质调查工作,为铁路工程地质遥感调查提供新的技术方法。该方法能够有效提高地质遥感调查的精度及质量,满足铁路工程不同勘察设计阶段的需求。

It is an important ways to use the remote sensing technology for railway engineering geological survey. But when only using single satellite data and traditional interpretation method, it could not get preferable survey effect because it could not satisfy the demands of geological survey in different survey stages. In order to improve the quality and efficiency of geological remote sensing survey of railway engineering, this paper discusses the multisource remote sensing technology used for railway geological survey, in which, different three dimensional interpretation environments should be established based on different remote sensing image data, and the geological survey should be carried out by means of muhi-image, multi-scale, and multi-angle. This can serve as a new method for geological remote sensing survey in railway engineering. And with this new method, the accuracy and quality of geological remote sensing survey can be improved effectively, and the demands in different survey and design stages of railway engineering can be accorded with.
