Abstract：Research purposes：Construction of the ballastless track of high-speed railway needs control network III (CPIII) for precise survey and control. For such control networks with high accuracy, the modern precise surveying devices should be adopted along with the optimum surveying scheme and reliable data processing for control of quality. This paper discusses the construction procedure and surveying scheme of CPIII and the corresponding data processing method for the first ballastless track high-speed railway from Beijing to Tianjin in China for providing the reference to the similar projects in future.
Research conclusions：The ballastless track control network based on free station and linear-angular intersection for high-speed railway is better than the general network in precision and network stability, which can satisfy the precise requirement of high-speed railway construction. The study and analyses of the surveying and data processing of CPII and CPI show the network with one surveying spot very 60m can satisfy the requirement of the track regularity and the control spot is restrained one time about very 500m can save money.
