摘　　要：鉴于公路建设里程长、跨度大等特点,单一坐标系统往往无法满足复杂的工程需求。基于此,文章通过分析多个公路工程案例,探讨了在不同地形条件下高效选择平面坐标系统的方法,研究成果对优化公路平面控制测量有重要的参考价值和实用意义。In view of the characteristics of long mileage and large span of highway construction,the single coordinate system is often unable to meet the complex engineering needs.Based on this,this paper discusses the method of efficient selection of plane coordinate system under different terrain conditions by analyzing several highway engineering cases.The research results have important reference value and practical significance for optimizing highway plane control survey.
