【摘要】：近些年，我國鋼橋制造業(yè)在計算機應用、先進設備的引進上有了巨大的進步和提高。為達到進一步探索鋼橋實現數字模擬預拼裝可能性的目的，本文采用德國GOM公司研發(fā)的TRITOP高精度光學三維定位測量系統(tǒng)，，測試預拼裝鋼橋構件，分析該系統(tǒng)的有效性。 本文首先應用TRITOP系統(tǒng)對常用的鋼橋構件在實驗室中進行測試研究，提出布點方案、拍照方案和TRITOP的計算方法等理論依據和測試方法，再借助中鐵山橋集團正在秦皇島山海關橋梁工廠進行預拼裝的某鋼桁梁橋的一個節(jié)段（工字梁G3、G4、箱型梁A1Y和節(jié)點板E2）進行實地測試研究，分析測試數據的統(tǒng)計特征，研究測點數量對精度分析結果的影響并進行測點優(yōu)化的分析，以期利用較少且合理的測點獲得完整有效的測試數據。 測試結果表明：本文提出的布點方案、拍照方案和TRITOP的計算方法是有效的；從橋梁工廠測試4根構件數據的正態(tài)分布圖可以看出測試數據布點對測試精度起著重要作用，測試構件制作精度主要來自切割、板厚和焊接變形的影響；考慮到標志點的作用和測試數據的離散情況，非編碼點的布置數量應不少于編碼點的布置數量，測點布置數量可以通過簡化同樣取得好的效果，當采用4、5、6個測點數量進行計算時，測試結果相比于整體樣本期望偏差較大，建議采用7~10個測點進行布置；現場測試鋼橋構件制作精度和孔群間距（含橫向、縱向的偏移值）等檢測項目符合規(guī)范要求。
[Abstract]:In recent years, the steel bridge manufacturing industry in our country has made great progress and improvement in the application of computer and the introduction of advanced equipment. In order to further explore the possibility of digital analog pre-assembly of steel bridges, this paper uses TRITOP high-precision optical three-dimensional positioning and measurement system developed by GOM Company of Germany to test the pre-assembled steel bridge components and analyze the effectiveness of the system. In this paper, we first use TRITOP system to test the commonly used steel bridge components in the laboratory, and put forward the theoretical basis and test method, such as placement scheme, photograph plan and TRITOP calculation method, etc. Then with the help of a segment of a steel truss bridge (I-beam G3G4, box girder A1Y and joint plate E2), which is being pre-assembled by Zhongtieshanqiao Group in Qinhuangdao Shanhaiguan Bridge Factory, the statistical characteristics of the test data are analyzed. The effect of the number of measuring points on the precision analysis results is studied and the optimization analysis of measuring points is carried out in order to obtain complete and effective test data by using fewer and more reasonable measuring points. The test results show that the proposed layout scheme, photographing scheme and TRITOP calculation method are effective, and from the normal distribution diagram of the test data of four components in the bridge factory, it can be seen that the test data placement plays an important role in the test accuracy. The fabrication accuracy of test components is mainly due to the effects of cutting, plate thickness and welding deformation; considering the function of mark points and the dispersion of test data, the number of uncoded points should not be less than the number of coding points, Good results can be obtained by simplifying the number of measuring points. When the number of 4 or 6 test points is calculated, the result of test is larger than the expected deviation of the whole sample, so it is suggested that 7 ~ 10 test points should be used for layout. In situ test of steel bridge component fabrication accuracy and hole group spacing (including horizontal and longitudinal offset) and other testing items meet the requirements of the specification.
