在处理边角网平差时，由于测边、测角相互独立，通常只能根据经验按观测类型不同进行验前方差估计，不能准确确定测边、测角观测量的权，影响了控制网的精确度。以高铁铺轨控制网（ CPIII ）数据处理为例，采用方差分量估计方法对控制网进行了数据处理和精度分析，并与等权处理方法做了比较，对边角网或其它不同类型的复杂控制网数据处理具有一定的参考价值。

In the processing of side-angle network adjustment, we cannot determine the accurate weight of the measurements because of the independent between the side and angle measuring.Generally, we get the prior estimate of variance based on the experience and observation type, which will affect the accuracy of control networks.In this paper, the writer take the data of the high-speed railway control network as an example, and use the variance component estimation to process the measurements and analysis accuracy, then compare the result with that of the equal weight method.This thesis has something referential value for the studying of processing of di-rection-distance or other complicated control networks.
