【摘要】：近年來(lái),鋼管混凝土拱橋以其優(yōu)美的外觀造型和獨(dú)特的結(jié)構(gòu)性能在我國(guó)得到了空前的發(fā)展,因其具有自重輕、強(qiáng)度高、承載能力大、結(jié)構(gòu)剛度大、施工安裝簡(jiǎn)便等優(yōu)點(diǎn)而廣泛應(yīng)用。 鋼管混凝土拱橋在其施工過(guò)程中結(jié)構(gòu)受力變化比較大,并且拱肋線形對(duì)拱橋的受力影響十分顯著。為了保證最終的成橋線形和受力滿(mǎn)足要求,必須在施工過(guò)程中對(duì)鋼管混凝土拱橋進(jìn)行施工監(jiān)控。 本文以浙江省天臺(tái)縣金盤(pán)大橋?yàn)楸尘?研究了鋼管混凝土拱橋施工控制技術(shù)中的相關(guān)問(wèn)題,包括施工過(guò)程中結(jié)構(gòu)變形、應(yīng)力等的監(jiān)測(cè)和控制。論文首先采用空間有限元法建立了金盤(pán)大橋鋼管混凝土拱橋的分析模型,對(duì)其關(guān)鍵的工況及受力性能進(jìn)行了分析,討論了拱橋施工控制的基本理論及方法,并根據(jù)金盤(pán)大橋的施工方法和受力特點(diǎn),研究制定了相應(yīng)的施工控制方案；其次,針對(duì)施工建設(shè)單位確認(rèn)的該鋼管混凝土拱橋施工的主要過(guò)程,進(jìn)行了鋼管內(nèi)混凝土灌注過(guò)程分析,并分別從應(yīng)力,變形和穩(wěn)定性三個(gè)方面進(jìn)行了詳細(xì)探討,同時(shí)在現(xiàn)場(chǎng)進(jìn)行了相關(guān)參數(shù)的監(jiān)測(cè)及有效分析控制；最后,論文還對(duì)金盤(pán)大橋施工過(guò)程中的吊桿張拉力進(jìn)行了監(jiān)測(cè)和控制研究,提出針對(duì)有推力的鋼管混凝土拱橋現(xiàn)澆橋面系縱橫梁結(jié)構(gòu)總體掛索張拉吊桿的方法,并對(duì)索力測(cè)試方法和公式進(jìn)行了對(duì)比分析并實(shí)施,結(jié)果表明所提出的監(jiān)測(cè)索力計(jì)算方法合理,達(dá)到了橋梁預(yù)定的設(shè)計(jì)施工要求。
[Abstract]:In recent years, Concrete-filled Steel Tube Arch Bridge (CFST) has been developed with its beautiful appearance and unique structural performance in China, because of its light weight, high strength, large bearing capacity and large structural stiffness. It is widely used because of the advantages of simple construction and installation. In the process of construction, the structure of concrete-filled steel tubular arch bridge changes greatly, and the influence of arch rib alignment on the stress of arch bridge is very significant. In order to ensure that the final shape and force of the bridge can meet the requirements, it is necessary to monitor the construction of concrete-filled steel tube arch bridge during the construction process. Based on Jinpan Bridge in Tiantai County, Zhejiang Province, this paper studies the related problems in the construction control technology of concrete-filled steel tubular arch bridge, including the monitoring and control of structural deformation and stress during construction. Firstly, the analysis model of concrete-filled steel tube arch bridge of Jinpan Bridge is established by using the spatial finite element method. The key working conditions and mechanical performance of the arch bridge are analyzed, and the basic theory and method of the construction control of the arch bridge are discussed. According to the construction method and stress characteristics of Jinpan Bridge, the corresponding construction control scheme is studied and established. Secondly, the main construction process of the concrete filled steel tube arch bridge confirmed by the construction unit is discussed. The process of concrete pouring in steel tube is analyzed, and the stress, deformation and stability are discussed in detail. At the same time, the relevant parameters are monitored and effectively analyzed and controlled in the field. The paper also studies the monitoring and control of the tension of the suspenders during the construction of the Jinpan Bridge, and puts forward a method for the overall cable tension of the cast-in-situ concrete filled steel tube arch bridge deck structure. The test method and formula of cable force are compared and analyzed. The results show that the calculation method of cable force is reasonable and meets the design and construction requirements of the bridge.
