摘要
针对传统方法的不足以及既有线提速后对线路养护的更高要求,参考国内外研究情况,文章对铁路提速线路绝对坐标测量控制网构建进行了精度研究和误差分析,提出了一些改进措施,对施测的具体流程进行了详细设计,希望对于当前我国铁路大提速情况下的铁路养护有所借鉴。
Against the deficiency of traditional methods and the higher maintenance requirements on the line after the acceleration of existing line,with the reference of research situation at home and abroad,this paper studies the procision and error of the absolute coordinate precision control network of speed lines,proposes some measures for improvement,designs the specific process of the surveying in detail,and hopes to provide some reference the railway maintenance under present circumstances of large-scale speed of railway in China.
