1、摘要高速铁路也称客运专线铁路，相比于传统铁路，客运专线铁路速度高达（200km/h～350km/h），为了达到在高速行驶条件下，旅客列车的安全性和舒适性，要求客运专线铁路必须具有非常高的平顺性和精确的几何线性参数，精度要保持在毫米级的范围以内。这就需要对轨道的几何尺寸以及结构有一个较完美的设计。本文首先介绍高速铁路的研究背景，然后利用自由设站边角交会观测方法测量数据，并进行间接平差计算，最后进行精度评定。本文研究内容如下：1.高速铁路研究的背景和高速铁路的发展历程，以及中国高速铁路与传统铁路的区别。2.对无
2、砟轨道CPIII平面网测量，CPIII平面控制网布设，CPIII控制点测量方法与上一级控制网的关系进行研究，并对外业测量方法仔细研究和分析，指出了相关的要求。3.给出CPIII网网型图，已知数据和平差数据。重点讨论将CPIII点当作近似坐标进行角度平差和距离平差，进而进行整体平差，计算出平差结果，并给出精度评定方法。介绍设计所运用的软件及相关知识。4.总结本次论文和对中国高速铁路未来的发展做出了展望。关键词：无砟轨道；高速铁路；测量；间接平差；CPIIIIIIAbstractHigh-speedrailwa
