新建海南东环铁路精密测量控制网

The precise survey control network of Hainan east ring railway

为保证新建海南东环铁路线下工程、轨道工程、接触网工程施工及运营管理等各阶段测量精度要求,建立沿线的CPI,CPII和CPIII精密测量控制网。介绍新建海南东环铁路精密工程测量控制网的创建技术依据、技术标准以及精度分析,阐述精密工程测量控制网的复测原则、数据处理分析方法,得到精测网复测与原测成果较差及复测结论,有效地保证了海南东环铁路工程施工的精度需要。

To ensure the required accuracy of all stages such as track - laying construction and operation of Hainan East Ring Railway, a CPI, CPII and CPIII precision measurement control network along the line was established. Firstly, this paper introduced the creation technical base, the technical standard and the precision analysis of new Hainan East Central Railway precision engineering surveying control network. Secondly, the check difference between the resurveyed and original measurement results as well as the conclusion of repetition measurement was derived through presenting the resurvey principle and a data processing analytic method of the precision engineering measurement control network, which effectively guaranteed the precision of engineering construction of Hainan East Central Railway.
