【摘要】：橋梁轉(zhuǎn)體施工是指將橋梁結(jié)構(gòu)在非設(shè)計(jì)軸線位置制作(澆注或拼接)成形后，通過轉(zhuǎn)體就位的一種施工方法。單T構(gòu)橋采用轉(zhuǎn)體施工，可以加快施工速度，節(jié)約成本，提高了安全性，減少了對(duì)既有線路運(yùn)營(yíng)的影響，近年來(lái)備受人們青睞。 本論文以杭州至長(zhǎng)沙(滬昆)鐵路客運(yùn)專線——江西省上饒市玉山縣湖沿特大橋(64+64) m單T構(gòu)水平轉(zhuǎn)體施工監(jiān)控項(xiàng)目為背景，簡(jiǎn)單介紹了橋梁轉(zhuǎn)體施工技術(shù)的發(fā)展、研究現(xiàn)狀和橋梁轉(zhuǎn)體施工控制的目的和意義。主要對(duì)無(wú)合龍段的單T構(gòu)橋的轉(zhuǎn)體施工技術(shù)將進(jìn)行研究，包括轉(zhuǎn)動(dòng)體系中的上轉(zhuǎn)盤、支撐腿、球鉸、環(huán)形滑道和牽引體系參數(shù)的計(jì)算，同時(shí)對(duì)轉(zhuǎn)體施工過程中的平衡稱重試驗(yàn)將進(jìn)行研究和監(jiān)控。 采用大型通用軟件Midas/Civil對(duì)簡(jiǎn)化后的滿堂支架模型簡(jiǎn)單的受力和變形進(jìn)行了分析及驗(yàn)算，通過Midas/Civil對(duì)主梁在滿堂支架施工過程中各施工階段的變形和應(yīng)力進(jìn)行了分析，并將其分析的最終鋪裝后的結(jié)果和橋梁博士3.0分析的結(jié)果進(jìn)行了對(duì)比。 最后，現(xiàn)場(chǎng)對(duì)梁體在落架及水平轉(zhuǎn)體過程中的內(nèi)力及變形進(jìn)行監(jiān)控，主要包括實(shí)施方法以及變形和應(yīng)力監(jiān)控結(jié)果的對(duì)比分析等內(nèi)容，從而為本橋的初轉(zhuǎn)和正式轉(zhuǎn)體的順利提供可靠的保證。 本論文對(duì)單T構(gòu)橋梁水平轉(zhuǎn)體施工技術(shù)進(jìn)行了詳細(xì)的計(jì)算和研究分析，對(duì)以后研究同類型的橋梁提供了一套完整的施工監(jiān)測(cè)和控制方法。最終華麗的轉(zhuǎn)“身”，表明了本監(jiān)控的準(zhǔn)確性，，本橋達(dá)到了滿足受力要求、線形平整的預(yù)期目的。
[Abstract]:The construction of bridge rotation is a construction method in which the bridge structure is made (pouring or splicing) in the non-design axis position, and then the bridge is rotated in place. The single T structure bridge can speed up the construction speed and save the cost by adopting the rotary construction. It improves the security and reduces the influence on the operation of the existing lines, and it is favored by people in recent years. In this paper, based on the construction monitoring project of Hangzhou to Changsha (Hu-Kun) railway passenger dedicated line-Lake side of Yushan County, Shangrao City, Jiangxi Province, the construction monitoring of horizontal transposition of single T structure is introduced, and the development of bridge transfer construction technology is briefly introduced. The present situation of the research and the purpose and significance of the construction control of the bridge rotation. This paper mainly studies the rotating construction technology of the single T structure bridge without closure, including the upper rotating disk, the supporting leg and the ball hinge in the rotating system. The calculation of the parameters of the annular chute and the traction system, and the study and monitoring of the balance weighing test during the construction of the rotary body will be carried out at the same time. The simple force and deformation of the simplified full support model are analyzed and checked by using the large and universal software Midas/Civil. The deformation and stress of the main beam during the construction stage of the full support are analyzed by Midas/Civil. The results of the final pavement analysis and that of Dr. Bridge 3.0 are compared. Finally, the internal force and deformation of the beam in the process of falling frame and horizontal rotation are monitored on the spot, including the implementation method and the comparative analysis of the monitoring results of deformation and stress, etc. Thus, it can provide reliable guarantee for the initial turn and official rotation of the bridge. This paper has carried on the detailed calculation and the research analysis to the single T-structure bridge horizontal rotation construction technology. This paper provides a complete set of construction monitoring and control methods for studying the same type of bridges in the future. Finally, it turns to "body", which indicates the accuracy of this monitoring, and the bridge achieves the expected purpose of satisfying the stress requirement and leveling the line shape.
