轨道控制网(CPⅢ)是高速铁路(简称高铁)建设中轨道铺设、安装调试控制和运营维护监控的基准。CPⅢ依据技术设计、建设需要,分测段建网,测段网衔接处理是CPⅢ建网技术的关键,其衔接处理将直接影响CPⅢ网成果精度和控制着轨道安装、调试及运营维护监测质量,为此把控测段网衔接技术是提高和保证CPⅢ建网质量的重要环节。
The track control network (CPⅢ) is the benchmark for track laying, installation, commissioning, control and operation and maintenance monitoring during the construction of high-speed railway (HSR). CP Ⅲ based on technical design, construction needs, sub-section of the establishment of network, section network convergence processing is the key CPIII network technology, the convergence will directly affect the CP Ⅲ network results and control the accuracy of rail installation, commissioning and operation and maintenance monitoring quality, To control the segment network convergence technology is to improve and ensure the quality of CPIII network construction an important part.
