正常水准面不平行性改正在铁路控制测量中的应用

The Application of Normal Level Surface Parallel Misalignment Correction in the Railway Control Survey

在阐述正常水准面不平行性原理的基础上,简要分析了这种不平行性对高差的影响情况;并结合具体工程项目,对控制测量复测成果进行了正常水准面不平行性改正,满足了《铁路工程测量规范》限差的要求,从而保证了控制网的精度。这可在类似工程建设中以做参考。

In elaboration normal level surface parallel misalignment principle foundation,the author analyzed this parallel misalignment briefly to the elevation influence situation,and carried on the normal level surface parallel misalignment correction to control survey repetition measurement data with combining the engineering project.This correction satisfied＂Railway Project Survey Standard＂the tolerance request,thus ensured the precision of the control network.This will provide the reference for the similar project construction.
