摘　　要：研究目的:铁路工程地质勘察过程中存在人工调查范围窄、外业劳动强度大、工作进度缓慢、质量难以保证的问题,遥感技术可以弥补地面调查的不足,辅助地质调绘和勘探布置,作用显著。但实际应用中由于遥感手段单一、目视解译精度有限而造成后期勘察阶段应用不深的现状,需要建立遥感勘察技术体系,达到精细指导地质测绘,提高铁路选线质量,减少外业工作量的目的。研究结论:(1)铁路遥感地质勘察技术体系由遥感图像选取、多源资料管理、图像解译、遥感评价和综合勘察等九大模块组成,形成了以遥感调查为主的新型工程地质勘察模式;(2)借助现代遥感多尺度对地观测技术和大比例尺解译技术,能够准确获取具有现势性的地质灾害、地表变化、人工活动等有效信息,补充了区域地质资料的不足;(3)铁路遥感地质勘察技术体系具有信息化、标准化和系统化的特点,可形成行业技术标准和作业程序;(4)本文的研究成果可适用于铁路选线、工程地质调查和勘探布置工作。Research purposes： In the progress of railway engineering geological survey, these issues exist that contain narrow artificial investigation range, great intensity labor, the slow pace of work, difficult to guarantee mapping quality. Remote sensing technique can significantly make up for the deficiency of the ground geological mapping, supplementary geological mapping and exploration arrangement. But in practical application, single method and limited visual interpretation precision cause remote sensing application not deep in late exploration stage, and need to further study on fine interpretation technique and detailed work program, to achieve the goals of accurately guide geological investigation and reduce the outdoor workload. Research conclusions： （ 1 ） Technology system of geological remote sensing consists of nine modules, which includes remote sensing image selection, multi - source data management, image interpretation, remote sensing assessment and integrated survey, formed a new model based remote sensing for railway geological survey. （2）With modern multi - scale remote sensing earth observation techniques and large -scale interpret technology, we can accurately obtain valid information of geological disasters, surface changes, labor activities, complements the regional geological data. （3）Technology system of geological remote sensing shows informatization, standardization and systematization characteristics, and forms industry technical standards and operating procedures. （4） The research results can be used in the railway line selection, engineering geological survey and exploration layout work.
