【摘要】：隨著公路橋梁的發(fā)展建設，橋梁結構的跨徑不斷增大，復雜性也隨之增大，施工質量與安全更加受到重視，施工監(jiān)控的重要性越顯突出。從已有文獻可知，由于結構的幾何狀態(tài)或受力狀態(tài)出現(xiàn)較大的誤差而引起的橋梁事故屢見不鮮。因結構各類設計參數(shù)、施工工藝及管理、溫度及收縮徐變等對結構的影響，必然會使實際狀態(tài)與理論狀態(tài)存在或多或少的誤差，所以設定一個合理的誤差標準以便于施工中對結構更好的監(jiān)控。然而橋梁施工監(jiān)控技術發(fā)展至今，還沒有制定相應的施工控制誤差標準。本文從以下方面對進行研究： ①對國內公路橋梁施工監(jiān)控誤差的研究現(xiàn)狀進行分析，本文通過統(tǒng)計歸納的方式對其進行研究。 ②簡述橋梁施工控制對可調變量誤差修正常用的理論和方法，結合已有橋梁結構對各方法的應用，分析比較各方法的優(yōu)缺點及其適用性，為今后施工監(jiān)控中誤差分析提供參考。 ③對武江大橋關于合龍誤差標準的分析，說明預先制定一個科學合理的施工施調誤差標準研究的必要性；通過收集已有梁式橋、拱式橋、斜拉橋、懸索橋施工監(jiān)控資料，，介紹了各類型橋梁監(jiān)控中應監(jiān)測的參數(shù)，以統(tǒng)計的方法對各參數(shù)誤差取值情況結合設計、相關現(xiàn)行規(guī)范綜合分析，提出公路橋梁施工監(jiān)控過程中各重點監(jiān)測參數(shù)的誤差施調標準范圍，為《公路橋梁施工監(jiān)控技術規(guī)范》制定提供依據(jù)。
[Abstract]:With the development and construction of the highway bridge, the span of the bridge structure is increasing, the complexity also increases, the construction quality and safety are more and more attention, and the importance of construction monitoring is more and more prominent. It is known from the existing literature that the bridge accident caused by the large error in the geometric state or the stress state of the structure is common. Due to the influence of various design parameters, construction technology and management, temperature and shrinkage and creep on the structure, it is necessary to make the actual state and the theoretical state more or less error, so a reasonable error criterion is set so as to better monitor the structure during construction. However, the construction and monitoring technology of the bridge has not been developed to date, and the corresponding construction control error standard has not been established. This article is a study of the following: The present situation of the monitoring error of highway bridge construction in China is analyzed in this paper. In this paper, the theory and method of the bridge construction control to the variable error correction are briefly described, and the advantages and disadvantages of the methods are analyzed and the applicability of the method is compared with the existing bridge structure. The error analysis in the future construction monitoring is provided. For reference, the analysis of the standard of the joint error of Wujiang Bridge is presented in this paper. It is necessary to develop a scientific and reasonable standard for construction and adjustment error in advance. By collecting the existing beam type bridge, arch bridge, cable-stayed bridge and suspension bridge, The monitoring data of each type of bridge is introduced. The parameters of each type of bridge monitoring are introduced, and the error value of each parameter is combined with the design according to the statistical method, and the relevant current standard comprehensive analysis is given. The error of each key monitoring parameter in the construction monitoring process of the highway bridge is put forward. The standard range is defined as the Technical Specification for Construction and Monitoring of Highway Bridges> System
