摘　　要：为保证高速铁路的安全运行,本文以某高速铁路运营期精测网复测项目为例,利用高程复测数据,分析高速铁路精测网复测时水准基点的稳定性方法,通过同精度内插完成高程成果的更新。通过分析计算,得出高程复测结论和成果,保证复测成果的精度和质量,利于后续轨道控制网(CPⅢ)高程的计算和应用,为类似项目提供参考。In order to ensure the safe operation of high speed railway,this paper takes the repetition project of precision engineering control network during the operation period of the high speed railway as an example,and uses the elevation repetition data analyse the stability method of the benchmark during the repetition of high speed railway engineering control network,and completes the update of the elevation results through the same precision interpolation.Through analysis and calculation,the conclusions and results of elevation repetition are obtained,which ensures the accuracy and quality of the repetition results,is conducive to the subsequent calculation and application of track control network CPⅢelevation,and provides a reference for similar projects.
