摘　　要：研究目的:将实测于某高速铁路客运专线的CPⅢ平面网数据分全盘位和半盘位分别进行平差处理,通过对CPⅢ平面网半盘位观测方式进行的可行性研究与分析,以期望能够用半盘位的观测方式来代替现在CPⅢ平面网全盘位观测的外业数据采集方式。研究结论:通过理论分析和采用大量CPⅢ平面网半盘位观测数据进行平差计算,并且与用全盘位观测数据进行平差计算的各项精度指标进行对比分析,证明能够用半盘位的外业观测方式代替现在CPⅢ平面网的全盘位的外业观测方式,这一研究结论可为《高速铁路工程测量规范》的修订与完善提供依据。Research purposes： The adjustment processing was made for the measured data from CPIIII plane network of one high-speed railway with full-face and half-face modes.The research and analysis were done and made for the feasibility of substituting half-face observation mode for the full-face observation on CPIII plane network for high-speed railway.Research conclusions：From the theoretical analysis,adjustment calculation with large amounts of the data of the half-face observation on CPⅢ plane network and comparison with all precise indexes of the adjustment calculation of the all-face observation data,it was concluded the half-face observation mode on CPIII plane network could substitute for the full-face observation mode.This research result could provide the basis for revision and improvement of the ＂Engineering measurement specification for high-speed railway＂.
