A data processing method for the precision surveying of ballastless track high-speed railway is put forward:first, choosing the compatible points in the control network by quasi-stable adjustment, then, adjusting the control network with the adjustment model of indirect observation in which the Baarda gross errors detection and Helmert variance component estimation are used.
提出一种适合无碴轨道高速铁路精密工程测量的数据处理方法:先采用拟稳平差选择兼容的起算点,然后应用间接平差模型平差;在平差过程中,用Baarda粗差探测的方法逐个剔除粗差,再用Helmert方差分量估计方法合理地确定边、角的权比。
