高速铁路框架控制网数据处理中基线解算模式分析

Modal Analysis of Baseline Solution Based on Data Processing of Frame Control Network of High-speed Railway

BASELINE和RELAX是GAMIT软件基线处理中两种不同的解算模式,为对比两种基线处理模式在高速铁路框架控制网数据处理结果,并确定何种基线处理模式更适用于高速铁路框架控制网的数据处理,应用BASELINE、RELAX基线处理模式进行基线处理,并采用TGPPS软件进行网平差,以均方根误差、基线重复性、基线较差、网平差等结果进行对比。结果表明,高速铁路长大干线的框架控制网基线解算中采用BASELINE效果较好。

BASELINE and RELAX are two different solution modes in GAMIT software baseline processing.In order to analyze the results of data processing of two baseline solution modes in the high-speed railway frame control network,determine the suitable baseline solution mode for the data processing of high-speed railway frame control network,and employ these two kinds baseline solutions to calculate the baseline,TGPPS software is used for network adjustment.The standardized root mean square error,baseline repetition,baseline difference,the network adjustment,and other indicators are comparatively analyzed.The results show that the BASELINE is better in the baseline solution model of frame control network of long-haul high-speed railway.
