工程测量中的坐标系选择原理与方法摘要摘要：近几年来，国家大力兴建高速铁路，由于高速铁路对边长投影变形的控制要求很高（2.5cm/km）,因而导致长期以来一直使用的三度带高斯投影平面之间坐标系已难以满足高速铁路建设的的精度要求，本文就具有抵偿高程投影面的任意带坐标系原理作出了阐释，具有抵偿高程投影面的任意带坐标系，克服了三度带坐标系在大型工程中精度无法满足要求的局限性，能有效地实现两种长度变形的相互抵偿，从而达到控制变形的目的。关键词：高速铁路、抵偿高程面、坐标转换、投影变形、高斯正形投影I工程测量中的坐标系选择原理与方法AbstractAbstract：Inrecentyears,countriesbuildhigh-speedrailway,duetohighspeedrailwayprojectivedeformationcontrolofreviseddemanding(2.5cm/km),andthereforecausehaslongbeenusedwiththreedegreesofgaussianprojectionplanesalreadydifficulttosatisfybetweencoordinatesystemofhigh-speedrailwayconstruction,thisarticletheaccuracyrequirementoftheplaneswithcounterelevationarbitrarymadeinterpretationwithcoordinatesystem,withtheprincipleofanyplaneswithanti-subsidyelevation,overcomethreedegreescoordinatewithcoordinatesysteminlargeengineeringaccuracycan'tsatisfyrequirementslimitation,caneffectivelyachievethetwolengthdeformationofmutualcounter,achievethepurposeofcontrollingdeformation.keywords：rapidtransitrailwayCounterelevationsurfaceCoordinatetransformationProjectivedeformationGaussianfounderformprojectionII工程测量中的坐标系选择原理与方法目录第一章前言..................................................................................................................1第二章工程测量中常用坐标系简介..........................................................................22.1国家统一的3〫高斯正形投影平面直角坐标系统....................................22.2抵偿高程面上的高斯正形投影3°带的平面直角坐标系统.......................32.3任意带高斯正形投影的平面直角坐标系统...............................................32.4具有高程抵偿面的任意带高斯正形投影平面直角坐标系...........................4第三章具有抵偿高程面的任意带高斯正形平面直角坐标系设计原理..................53.1高斯正形投影..................................................................................................53.2投影变形及其主要特特征分析......................................................................63.2.1将参考椭球面上的长度归化至高斯平面.........................................................63.2.2将参考椭球面上的长度归化至高斯平面..................................................73.3设计原理........................................................................................................................73.4工程测量投影面和投影带选择的基本出发点8第四章实例比较与分析............................................................................................9第五章总结..............................................................................................................10参考文献..........................................................................................................................11致谢..................................................................................................................................12附录..................................................................................................................................12III第1页共25页编号：时间：2021年x月x日书山有路勤为径，学海无涯苦作舟页码：第1页共25页工程测量中的坐标系选择原理与方法Engineeringmeas...
