摘要在工程建设的勘测、施工中常常涉及到高程测量,现场采用的测量方法主要是水准测量和三角高程测量。水准测量精度高,但是速度比较慢,效率低。此外,水准测量的转点多,而且标尺与仪器也存在下沉误差,如果在丘陵、山区等地使用水准测量进行高程传递是非常困难的,有时甚至是不可能的。近些年来,由于全站仪的发展,使得测角、测距的精度不断提高。三角高程测量传递高程比较灵活、方便、受地形条件限制较少等优点,因此全站仪三角高程测量补充了水准测量不能在山区等地形起伏较大的地区施测的不足,成为水准测量的重要方法。本文对全站仪三角高程测量的原理、方法、精度等进行了分析,认为用全站仪代替水准仪进行高程测量,在一定范围内可达到三等水准测量要求。关键词:全站仪三角高程精度分析等级水准AbstractIntheconstructionsurvey,constructionofteninvolvetheheightmeasurement,thesceneisthelevelingmeasurementmethodismainlyusedandtrigonometricleveling.Levelingprecision,butataslowerspeed,lowefficiency.Inaddition,theturningpointoflevelingandgaugeandinstrumentisalsosinkingerror,ifinthehills,mountainsandotherplacesusingthelevelingelevationtransferisverydifficult,sometimesevenimpossible.Inrecentyears,duetothedevelopmentofthetotalstation,theaccuracyofAngle,distancetoimprove.Trigonometriclevelingelevationismoreflexibleandconvenient,andtheadvantagesoflessrestrictedbyterrainconditions,sothetriangleelevationsurveyingaddedlevelingcan'tinmountainousterrainvolatileregionssuchasmeasuredbytheinsufficiency,hasbecomeanimportantmethodofleveling.Inthispaper,theprincipleandmethodoftotalstationtriangleelevationmeasurement,precisionareanalyzed,suchasthatusingtotalstationtoreplacethelevelheightmeasurement,withinacertainrangecanbeuptothree,thefourthlevelmeasurementrequirements.KeyWords:Totalstation,Triangleelevation,Accuracyanalysis,Orderleveling目录TOC\o"1-3"\h\zHYPERLINK\l"_Toc423089261"摘要PAGEREF_Toc423089261\hIHYPERLINK\l"_Toc423089262"AbstractPAGEREF_Toc423089262\hIIHYPERLINK\l"_Toc423089263"第1章绪论PAGEREF_Toc423089263\h1HYPERLINK\l"_Toc423089264"1.1前言PAGEREF_Toc423089264\h1HYPERLINK\l"_Toc423089265"1.1.1研究目的与意义PAGEREF_Toc423089265\h1HYPERLINK\l"_Toc423089266"1.2国内外研究现状PAGEREF_Toc423089266\h2HYPERLINK\l"_Toc423089267"1.2.1国内研究现状PAGEREF_Toc423089267\h2HYPERLINK\l"_Toc423089268"1.2.2国外研究现状PAGEREF_Toc423089268\h3HYPERLINK\l"_Toc423089269"1.3本文研究内容PAGEREF_Toc423089269\h3HYPERLIN
