摘　　要：介绍了高速铁路轨道基准网平面网所采用的德国测量及其相应的数据处理方法,并指出了其存在的不足之处;在此基础上,提出了测量效率更高、平差过程严谨、能够进行精度评定的构网法测量及其严密平差方法;对提出的新方法进行了相邻点相对点位精度估算,并且在模拟轨道基准网上分别对2种方法进行了对比观测实验。理论研究和对比分析后认为构网法可以用于轨道基准网平面网的测量及其严密平差计算,而且具有多方面优势,可供有关部门参照和使用。The paper first introduced the German measurement and data processing method used in the plane network of Track Reference Network of high-speed railway,and pointed out the inadequacies of its existence.On basis of German method,a new method,named network-constructed measurement,with its data processing method was put forward,which is more efficient,strict in adjustment calculation process and capable of accuracy evaluation;Finally,the paper estimated the relative point precision of the proposed new method,and had a compared experimental observations on the simulation of the Track Reference Network.After the theoretical research and comparative analysis,the network-constructed measurement are available in the plane network of Track Reference Network of high-speed railway,which also has many advantages,and can be referenced and used by the relevant departments.
