內(nèi)蒙古科技大學 本科生畢業(yè)設(shè)計 說明書 ( 畢業(yè) 論文) 題 目: 地面控制網(wǎng)的布設(shè)和精度分析 學生姓名: 孫世超 學 號: 1179204101 專 業(yè): 測繪工程 班 級: 2 班 指導教師:燕志明 內(nèi)蒙古科技大學畢業(yè)設(shè)計說明書 (畢業(yè)論文) I 摘要 本文主要分為三個部分 , 第一部分概括分析了現(xiàn)代控制測量的研究意義和現(xiàn)狀 , 第二部分總結(jié)整理了國家控制網(wǎng)和工程控制網(wǎng)的布設(shè)方法 、 布設(shè)原則等內(nèi)容 ,第三部分通過平差的計算對大地四邊形控制網(wǎng)的布設(shè)方法和閉合導線的布設(shè)方法做出了精度分析 。 現(xiàn)代控制測量已經(jīng)逐漸趨于成熟,近代平差理論經(jīng)過一代代測量人的研究得到 極大的發(fā)展,并能夠在工程實踐中與工程控制網(wǎng)布設(shè)相結(jié)合,是工程控制網(wǎng)更加趨向穩(wěn)定、精密。隨著現(xiàn)代電子計算機技術(shù)的發(fā)展,并逐漸應(yīng)用于控制網(wǎng)布設(shè),使得控制網(wǎng)的優(yōu)化更加簡單。 本文的第二部分,主要介紹了平面控制網(wǎng)與高程控制網(wǎng)的布設(shè)原則、布設(shè)方法以及具體的不設(shè)方案。控制網(wǎng)分為平面控制網(wǎng)和高程控制網(wǎng) ,而國家布設(shè)的平面控制網(wǎng)跟工程上用的平面控制網(wǎng)也有著很大的區(qū)別,在文章里也有具體的闡述,本文的最后,對大中礦區(qū)大地四邊形和閉合導線兩種布設(shè)方案進行了平差和精度分析。 關(guān)鍵詞:國家平面控制網(wǎng) ; 工程平面控制網(wǎng) ; 國家高程控制網(wǎng) ; 精度分析 內(nèi)蒙古科技大學畢業(yè)設(shè)計說明書 (畢業(yè)論文) II Abstract This paper is divided into three parts, the first section summarizes the analysis of the significance and status of modern control measure, finishing second section summarizes the methods laid state control work and control work engineering, layout principles content, the third part through the adjustment The calculation method laid the earth quadrilateral control wire mesh and closing the layout made a precision analysis methods. Modern control measure has been gradually maturing, generations after adjustment theory of modern human studies measuring tremendous growth, and can be bined with engineering control work laid in engineering practice, is the engineering control works tend to be more stable and precise. With modern puter technology, and gradually used to control work deployment, making optimization control work easier. The second part of this paper introduces the principle of horizontal control work layout and elevation control work, laying methods and no specific program. Control work is divided into horizontal control work and elevation control work, while the state control work laid flat on a plane with engineering control work also has a big difference, in the article, there are specific elaboration, finally, for medium and large mines of this article geodetic quadrangle and closed two disposition programs lead the adjustment and accuracy analysis. Keywords: National plane control work。 Engineering plane control work。 National elevation control work。 Accuracy analysis內(nèi)蒙古科技大學畢業(yè)設(shè)計說明書 (畢業(yè)論文) 目錄 摘要 .................................................................................................................................
