对实测于某高速铁路CPIII平面网的半盘位数据及其自由设站测量的数据进行平差处理,以CPIII平面网验后精度指标和高铁自由设站精度要求为依据,对平差结果的精度进行一系列的统计与分析,半盘位CPIII平面网的精度,不仅能够满足CPIII平面网的各项精度要求,而且能够满足高铁自由设站测量的精度要求。通过理论分析和实验数据,证明CPIII平面网半盘位测量方法具有可行性,据此提出CPIII平面网测量的新方法,具有测量效率成倍提高的优势,应该在高铁CPIII平面网实际测量中推广使用。
The data of the half-disc measured in a high-speed railway CPIII plane network and the data of its free standing station are adjusted. Based on the CPIII plane net post-inspection precision index and the high-speed rail free station setting requirements, Accuracy of a series of statistics and analysis, the accuracy of the half plate CPIII plane network, not only to meet the CPIII plane network of the accuracy requirements, but also to meet the high-speed rail free station measurement accuracy requirements. Through theoretical analysis and experimental data, it is proved that the method of measuring the half-plate of CPIII flat screen is feasible. Based on this, a new method of CPIII flat-screen measurement is proposed, which has the advantage of doubling the measurement efficiency and should be popularized in the practical measurement of the high-speed railway CPIII plane net use.
