高速铁路轨道控制网高程网测量新方法

New method for elevation network measurement of high-speed railway track control network

目前高速铁路轨道控制网(CPⅢ)高程网的水准测量方法有德国的中视法和我国的矩形法。但这2种方法在测量实际中的效率并不够高,需进一步改进当前的测量方法提高生产效率。基于高精度的电子水准仪单次测量数据的精度和可靠性高的考虑,提出1种外业测量效率更高的电子水准仪CPⅢ高程网测量新方法。通过介绍该方法的外业测量原理和数据处理过程,阐述采用该方法获取外业测量数据的可靠性,同时研制该方法的数据处理软件并且用于实例计算。研究结果论证了该方法的可行性,建议在高速铁路工程测量规范修订时引进该方法并在实际工程中应用。

Currently there are two main methods for elevation network level measurement in high speed railway track control network （CPIII ）,namely,German intermediate sight method and the China rectangular method. However,in the measurement process of CPIII elevation network,the two methods are not efficient,which needs to further refine the current measurement method to improve the production efficiency.Based on the consideration of the accuracy and reliability of the single measurement data measured by high precision electronic level,a more ef-ficient electronic level CPIII elevation network measurement method was proposed in this paper.The field measure-ment principle and data processing process of the method were introduced,and the reliability of field measurement data was interpreted by this method.Moreover,data processing software of the method was developed,which was then used to calculate an actual calculation.Through computational analysis and comparison of measurement exper-imental data,the results demonstrate the feasibility of this method,and it is suggested to add this method in the re-vision of high-speed railway engineering surveying specifications and to apply it to practical engineering.
