Deformation of bridge engineering also bee the focus of concern. Research on bridge engineering deformation monitoring is the flexible structure and its dynamic characteristics are, diagnosis report for Bridge Engineering signs of life, so that people can be an antidote against the disease, to avoid the occurrence of major accidents.Firstly, development and significance of bridge engineering deformation monitoring is summarized, and several methods of deformation monitoring of bridge engineering are briefly described. Through the study of deformation monitoring for Nanfeng County of Jiangxi province Fuzhou City Nuo Xiang Bridge and its data， using ground survey method of data collection and analysis. According to the deformation monitoring during the construction of Nanfeng County of Jiangxi province Fuzhou City Luo Xiang Bridge and the pletion of the. The real and vivid description of the application of deformation monitoring in the bridge construction.Key Words: Bridge Construction。 Deformation Monitoring。 Safety Misadventure東華理工大學長江學院畢業(yè)設(shè)計（論文） 目錄目 錄1 緒 論 ................................................................................................................................1 橋梁變形監(jiān)測發(fā)展歷程及意義 ............................................................................1 橋梁變形監(jiān)測的主要方法和研究進展 ................................................................1 橋梁變形觀測的主要內(nèi)容 ....................................................................................2 橋梁工程變形觀測安排 ........................................................................................2 塔柱變形觀測 ................................................................................................2 橋面撓度觀測 ................................................................................................3 橋面水平位移觀測 ........................................................................................32 橋梁變形監(jiān)測 ....................................................................................................................4 變形監(jiān)測的原理 .....................................................................................................4 統(tǒng)計分析法 ....................................................................................................4 確定函數(shù)法 ....................................................................................................4 橋梁變形的限制 .....................................................................................................5 主梁撓度變形限值 ........................................................................................5 墩臺沉降變形限值 ........................................................................................5 橋梁變形的分類 .............................................................................................6 橋梁靜態(tài)變形監(jiān)測 .................................................................................................6 系統(tǒng)布置 .................................................................................................................6 橋墩沉陷與橋面線形觀測點的布置 .............................................................6 塔柱擺動觀測點布置 .....................................................................................6 水平位移監(jiān)測基準點布置 .............................................................................6 垂直位移監(jiān)測基準網(wǎng)布置 .............................................................................73 橋梁工程變形監(jiān)測具體實施方法與精度 ........................................................................8 GPS 定位系統(tǒng)測量平面基準網(wǎng) .........................
