毕业设计__两种贯通方法误差预计程序设计..docx

摘要现在市场上没有一款正式发布的软件明确支持地下贯通误差预计，并且实际工作中使用图解法或者Excel计算繁琐复杂，在特大型贯通中又有些力所不足。基于此，本文主要使用C++语言，设计井下两种贯通方法（一井贯通和两井贯通）误差预计程序。程序直接读取点数据文件和按约定原则的贯通信息数据文件（txt文本格式文件），计算贯通点在重要方向上的误差值，极大的减少处理数据和计算繁琐度。并且改变了在增添或者删除加测陀螺定向边情况下就需要大规模重新计算的局面，使贯通测量设计提高效率。整个使用的误差预计公式，为现在贯通误差预计中使用最久最成熟的导线法误差预计公式。程序主要由两个大类，一是支导线误差预计类，二是加测陀螺定向边的方向附合导线误差预计类组成。通过main主函数的调用，简单组合，实现程序最大的灵活性。而每个类由主要的五个成员函数构成，使程序简明。最后以文本格式输出贯通误差预计详细结果和预计处理过程的相关数据。不仅对实际误差预计工作有现实意思，也为编制测量程序积累了经验。关键字：导线法贯通误差预计程序AbstractNowadays,We can’t find a software that released officially supporting estimation of through error underground in the surveying and mapping market.Besides,using graphical method or Excel to calculate during the practical work is complicated.It’s inefficient in the large-scale break through survey.Therefore,this article will design program to solve error prediction of two back through ways(single shaft orientation and two shaft orientation).The program can directly read data files and break through information data files (.txt) according to the contract.It can calculate the error value of holing point on the important direction which greatly simplify the process. It also change the situation where need to a large scale recalculate in the case of adding or deleting gyroscopic directed edges which can improve efficiency in through survey.The error prediction formula the program use is the most longer and mature formula in break through error prediction.The program conclude two parts:error prediction of branch conductor and direction-connecting traverse which has gyroscopic directed edges.By calling main function,simply combining,the program achieve great flexibility.Each class has five member function makes the program simple and clear.Finally it can output the result and related data of error prediction process.This article is not only meaningful to the actual work,but also a useful experience for measurement program writing.Keywords: Wire; error prediction ;through ;software1.绪论1.1研究背景及意义随着国际隧道协会（IAT）提出“大力发展地下空间，开始人类新的穴
