摘　　要：包头—银川高铁通过区域走廊方案呈"田"字分布,线路方案复杂,研究宽度经向维向相当,且地质问题散乱众多,因此,将遥感数字技术新方法用于铁路地质工作,从而快速准确筛选出控制各路线方案的地质重点、难点,从专业技术的角度评价各方案、支线、枢纽及局部比选方案地质条件和特点,为包银高铁选出最佳方案提供技术支撑很有必要。应用卫星3D地图、"大场景"、航空航天遥感或地面遥感、无人机摄影等数字技术新方法实现室内与野外的互动,研究经过黄河河套区和高原沙漠区两大类地貌的各方案的主要工程地质问题和项目重点、难点技术,进行动态解译,给出地质选线意见,最终推荐A1K方案。新方法在线状、面状工程的地面及地下地质研究方面均可应用,具有用时短、精度深、效率高的特点,可为类似工程研究提供借鉴。Baotou-Yinchuan high-speed railway regional corridor plan is shaped like a Chinese character“田”,which makes the routing rather complex with messy geological problems.Therefore,it is necessary to apply digital remote sensing technique to railway geological works to allow fast and accurate screening of critical and difficult points in routing control schemes,evaluation of geological conditions and characteristics on routing,branch lines,traffic hubs and local schemes comparison from a professional point of view,and thus provide technical support for optimal scheme selection of Bao-Yin Railway.This paper utilizes such digital technologies as 3D satellite mapping,“large scene”technique,space or ground remote sensing and drone photography to achieve indoor and field interactions.Furthermore,the main geological engineering problems and pivotal techniques regarding topography of Hetao region of the Yellow river and Plateau desert area are studied with dynamic interpretations,opinions on geological route selection are presented and A1K plan is finally recommended.The new approach is applicable to the study of surface and underground geological conditions of both linear and areal projects with short time span,high accuracy and efficiency,which can provide references for similar engineering researches.
