通过对高速铁路轨道平面控制网(CPⅢ)测量原理的分析和讨论,揭示了高速铁路轨道平面控制网是一种自由设站的导线测量。针对高速铁路轨道平面控制网的名称问题,建议将自由测站边角交会法改为自由设站导线测量法。 Through the analysis and discussion of the measurement principle of the high-speed railway track plane control network (CPIII), it is revealed that the high-speed railway track plane control network is a kind of free-standing station wire measurement. In view of the name of the plane control network of high-speed railway track, it is suggested to change the free cross-border rendezvous method to the free standing station wire measuring method.
