高铁轨道基准网三角高程网构网及数据处理方法研究

本文首先介绍高速铁路轨道基准网、高程网测量及其数据处理的德国方法,通过分析德国方法的不足,提出一种轨道基准网三角高程网及其数据处理的新方法,并详细介绍了其构网的模型与数据处理的过程。通过仿真计算和观测试验,对轨道基准网三角高程网的可行性进行了验证,认为其可以取代目前的轨道基准网水准网,而且效率高,能够进行精度评定并具有自主创新的优点。

Study on Establishing Network and Data-processing Method of Trigonometric Levelling Network for Track Reference Network of High Speed Railway

The paper first introduced the German method about the leveling network measurement and data processing in track reference network of high-speed railway,which finally put forward a new method for trigonometric leveling network of track reference network by analyzing shortcomings of German method in some aspects and presented its procedure of establishing network and processing data in details.Through the simulation calculation and experiments,this paper proved that the new method is practicable,the result of which showed that the new method can replace the current methods and has the advantages of high efficiency,accuracy assessment and independent innovation.
