摘　　要：在高等级导线控制桩基础上,对铁路中线测设方法进行探讨。在实际工程放线中,运用全站仪按极坐标法进行作业,建立假定坐标系计算导线控制桩坐标,开发应用程序进行测设,提高工作效率。This paper discusses the surveying and setting method of railway centerlines using advanced traverse control as basic control.In the actual engineering setting out,the author uses the total station to operate according to the polar coordinate method,calculates the coordinates of traverse control piles by establishing assumed the coordinate system,develops the application program,and greatly improves the work efficiency.
