摘　　要：陡峭地区线路勘察设计中存在地形变化大、安全性差、测量频繁、断面信息人工提取工作量大等问题。为此,提出一种利用空间信息技术进行线路两侧断面信息自动提取的方法,实现了线路两侧点位的精确采集、两侧点位的自动归中计算以及断面信息的自动生成。经过在西纵高速公路线路勘察设计生产项目中的实际应用,取得了良好的效果,验证了该方法的可行性及实用性,为今后类似工程的开展提供辅助支撑。In view of the characteristics of large topographic variation,poor safety,frequent survey and heavy manual work in steep area,a method of automatic extraction of section information on both sides of the line by using spatial information technology is proposed,which realizes the automatic sectional data calculation and automatic extraction of the section information on both sides of the line.After being applied in XiZong Expressway project,good results have been achieved,which verifies the feasibility and practicability of this method and provides auxiliary support for the development of similar projects in the future.
