摘要
首先介绍任意设站控制网测量在城市轨道交通铺轨中的应用现状,基于“自由设站”的原理提出轨道交通铺轨加密三角高程测量及其数据处理方法,并详细介绍了其构网模型与数据处理原理。通过观测实验对新方法的可行性进行验证,为现有轨道交通铺轨高程加密测量与数据处理方法的改进提供参考。
This paper firstly introduces the application status of control network measurement with arbitrary stations in urban rail transit rail laying,and based on the principle of“free station setting”,proposes the rail transit rail laying encryption triangulation elevation survey and its data processing method,and introduces its network construction model and data processing principle in detail.The feasibility of the new method is verified by observation experiments,which provides a reference for the improvement of the existing measurement and data processing methods of rail transit laying elevation encryption.
