从新疆某长距离输气管道测量工程问题说投影改正

DISCUSSION PROJECTION CORRECTION FOR A XINJIANG LONG-DISTANCE TRANSPORT NATURAL GAS-PIPE SURVEY PROJECT PROBLEM

针对新疆某长距离输气管道工程测量工程用户投诉的问题,本文阐述了近几年长输线路工程测量项目的特点。根据现代长输线路工程测量应用技术——卫星定位技术(GPS)和电磁波测距技术的应用原理,从理论上探讨和分析可能产生问题的各项原因;借助投影改正计算模型的分析和计算,达到解决用户投诉的问题的目的;希冀由此给业界类似工程的类似问题以借鉴。

According to the survey of problems of distant transport natural gas pipe project in Xinjiang,the characteristics of the survey of the distant transport line project in the past few years are expounded in the paper.The causes that may be likely to bring up problems are discussed and analyzed on the basis of the modern times long transport line project survey including GPS and Electromagnetic Wave Measure Distance.The problems of the consumers are settled by using analyzing and summing Projection Correction model and model calculation,which provides aguidance for samilar problems in this field.
