摘　　要：针对传统既有铁路曲线重构方式图形化交互程度低,无法实现既有铁路图形和属性数据的统一管理,从而导致曲线重构步骤繁琐的问题,利用GIS建立了既有铁路曲线重构系统,实现了既有铁路图形和属性数据的一体化管理、数据查询以及既有铁路正交最小二乘曲线重构。计算实例表明,该图形化作业方式人机交互方便、操作简单、效率高,能快速实现既有铁路曲线重构,重构曲线的拨正量能满足精度要求,拟合结果更加接近工务台账,具有很好的用户体验。The graphical interaction degree of the traditional railway curve reconstruction method is low, and the unified management of the existing railway graphic and attribute data cannot be achieved, which leads to the problem of complicated curve reconstruction steps. In order to solve these problems, we used GIS to build an existing railway curve reconstruction system, to achieve the existing railway graphic and attribute data integration management, data query and curve reconstruction by orthogonal least squares. The calculation example shows that the graphical operation mode has the advantages of convenient man-machine interaction, simple operation and high efficiency, and can quickly achieve the existing railway reconstruction. The fitted result is closer to the ledger, which is a good user experience.
