论高速铁路精密工程测量“三网合一”

客运专线铁路对测量精度要求较高,传统的分阶段布网方式和方法已不能满足现代高速铁路建设的需要。文章提出了＂三网合一＂的测量体系和布设原则及控制网的精度梯度等级,该体系的建立能统一高速铁路勘测控制网、施工控制网、运营维护控制网的起算基准和协调其精度,保证无碴轨道铁路工程的顺利实施。

On High-speed Rail Precise Engineering Survey of Three Networks in One

The passenger-dedicated railway lines require strictly precise survey.The traditional way of phased arrangement of network cannot meet the need of the construction of modern high-speed railway.The paper suggests＂Three Networks in One＂survey system,arrangement principle and precise gradient of controlling network.Such system can unify initial benchmark of the survey-controlling network,construction-controlling network of high-speed railway and harmonize their precision, further,guarantee the project of ballastless track can be implemented smoothly.
