测绘工程毕业论文--GPS_RTK在道路桥梁中的应用-常用导线的编程.docVIP

摘 要 当前，我国经济形势大好，国内建设飞速发展，各种大型工程(如铁路、公路、桥梁等)纷纷上马，由于常规测量技术不能满足快速、准确、高效的要求，加上GPS自身的特点，GPS在路桥工程中的应用越来越广泛，利用GPS建立路桥工程施工控制网已普遍展开。由于工程控制网的一些自身特性，使得GPS在路桥工程中的应用也有一些特殊性。本文介绍了GPS全球定位系统的建立，GPS系统的组成，GPS系统的原理，以及GPS导航定位误差，着重阐述了RTK技术的基本原理，RTK的组成及工作条件，以及RTK测量的精度和误差来源，并结合具体的例子——GPS-RTK在苏通长江大桥中的应用，详细阐述了RTK技术在桥梁施工方面的应用，通过分析例子说明RTK技术的优点并提出了RTK技术作业过程中存在的一些问题，和它在测量方面局限性和今后的发展方向。 关键词：GPS； RTK技术； 工程测量；桥梁； Abstract At present， our country the economic situation be greatly good, the local construction flies to soon develop, various large engineering(like railroad, highway, bridge...etc.) ascends a horse in succession, because of normal regulations measure the technique cant satisfy quickly, accurate, efficiently of request, plus the characteristics of GPS oneself, the GPS is in the road bridge application within engineering more and more extensive, make use of the engineering construction of the GPS establishment road bridge control net already widespread launch.Because the engineering control is some oneself characteristics of the net, make the GPS also have some special in the road bridge application within engineering.This text introduced the establishment of fixed position system in the GPS world, constitute of GPS system, the principle of the GPS system, and the GPS navigate fixed position error margin, emphasized to elaborate the RTK technical basic principle, constitute of RTK and work condition, and RTK measure of accuracy and error margin source, and combine concrete example-GPS-RTK an application within Yangtze River Bridge at Su, elaborated in detail the RTK technique starts construction in the bridge aspect of application, pass analysis example to explain the advantage of RTK technique and put forward a little bit existent problems in the RTK technique homework process, limit the development direction in sex and aftertime with it in the aspects of measure.
