摘　　要：为了有效地满足高速铁路轨道的高平顺性、高精度以及高速行车安全的要求,利用GPS先进技术进行高铁CP0、CPI、CPII控制网的布设、观测及数据处理,首先对传统铁路测量方法和高速铁路测量方法进行了比较,之后提出了高铁CP0、CPI、CPII控制网的观测方法及TGO数据处理方法.研究结果表明:该方法满足了线上工程可靠性强、精度高的技术要求.该方法为一种全新的测量方法及作业理念,必将对高速铁路工程测量相关规范的制定和高速铁路控制网建立的自动化、信息化起到重要作用.In order to effectively meet the requirements of high smoothness, high precision and high safety for high-speed traffic in high-speed railway, this study uses a GPS technology to establish CP0, CPI and CPII controlling networks for high-speed railway, and obtains and processes the survey data. Based on the comparison between the survey methods for conventional railway and high-speed railway, the study proposes a survey method of the CP0, CPI and CPII control networks for high-speed railway and a TGO data processing method. The methods proposed attain the technical requirements of strong reliability and high precision for railway line project. The result demonstrates that the method proposed is a new survey method and operation philosophy, which will play a significant role in formulating relevant standards of engineering survey, and in the automation and informatization of control network establishment for high-speed railway.
