结合中铁十五局京沪高速铁路CRTSⅡ型板式无砟轨道精调测量施工经验,从轨道几何形态描述、轨道几何形态参数测量原理和测量要点、精测数据内业分析处理等几个方面对轨道精调测量技术进行分析总结,认为在测量过程中要特别注意以下两点：全站仪设站的位置应靠近线路中线,并且与近处控制点的距离至少大于15m;变更基准轨确定方法。%Upon the basis of the construction experience from the fine adjusting and surveying skills for Type-CRTS Ⅱ ballastless,slab-type tracks used for the Beijing-Shanghai Express Railway,the construction of which is contracted to the 15th Bureau Group Corporation,the fine adjusting and surveying skills for laying the tracks are analyzed and summed up in the paper from the angles of the description of their geometric shape,parameters and principles of surveying their geometric shape,and important points for surveying the geometric shape of the track,and data analysis and processing of the fine surveying.From the summarization,it is concluded that special attention should be paid to two points：the total electronic station should be positioned as close to the mid-line of the railway as possible and at least more than 15m away from the surveying points,and the determining method for the base track should be changed.
