| Abstract: | he ballastless track of high speed railways should be of good stability, continuity and high evenness. High accuracy three dimensional control survey technology is needed in the construction of the ballastless track. Taking the survey practice in Feiluan Tunnel on Wenzhou Fuzhou Railway and Jiuniushan Tunnel and Fenghuangshan Tunnel on Ningbo Taizhou Wenzhou Railway as example, the author presents the characteristics, technical requirements and survey method of CPIII control points survey technology for the ballastless track of high speed railways and makes analysis on some survey errors. |
