【摘要】：進(jìn)入新世紀(jì)，我國(guó)經(jīng)濟(jì)取得了突飛猛進(jìn)的發(fā)展。隨著我國(guó)經(jīng)濟(jì)的發(fā)展，我國(guó)將進(jìn)一步完善社會(huì)基礎(chǔ)設(shè)施建設(shè)，因此這給我國(guó)橋梁事業(yè)的發(fā)展帶來(lái)了前所未有的發(fā)展機(jī)遇。然而，如何運(yùn)用好這次發(fā)展，對(duì)于我們來(lái)說(shuō)事關(guān)重要；如何安全的對(duì)橋梁進(jìn)行施工，避免施工過(guò)程中事故的發(fā)生，，對(duì)于我們來(lái)說(shuō)更加重要。斜拉橋以其優(yōu)美的線形、強(qiáng)大的跨越能力等優(yōu)點(diǎn)，得到了橋梁界的青睞。然而斜拉橋的施工與其他橋梁有著很大的不同，其施工過(guò)程中不僅涉及到主梁的施工，而且涉及到斜拉索的安裝等工作，因此斜拉橋的施工安全越來(lái)越受到社會(huì)大眾、橋梁工作者的重視。 本文以邢臺(tái)市南水北調(diào)總干渠的中興大街景觀橋?yàn)楣こ桃劳校芯啃崩魉髁Φ臏y(cè)量方法，特別是基于振動(dòng)測(cè)量的索力計(jì)算方法；研究橋梁施工方法與監(jiān)控方法。在斜拉橋的施工中，主梁、橋塔、拉索的施工是施工中的重點(diǎn)。在施工監(jiān)控作中，可以通過(guò)開(kāi)環(huán)控制、反饋控制、自適應(yīng)控制等監(jiān)控思路來(lái)確定監(jiān)控方案，通過(guò)倒拆法、正裝迭代法、無(wú)應(yīng)力狀態(tài)法、影響矩陣法等方法來(lái)確定合理施工狀態(tài)。 本文詳細(xì)的介紹了中興大街景觀橋的MIDAS有限元模型的建立過(guò)程及施工階段的劃分，分析了中興大街景觀橋主梁和斜拉索的施工方法，研究制定了中興大街景觀橋的施工監(jiān)控內(nèi)容、重點(diǎn)及方法，并對(duì)橋梁施工過(guò)程中的測(cè)量數(shù)據(jù)結(jié)合有限元分析結(jié)果進(jìn)行了分析，為大橋的順利竣工提供了有利的保障。
[Abstract]:Entering the new century, China's economy has made rapid progress. With the economic development of our country, our country will further perfect the construction of social infrastructure, so this brings unprecedented development opportunity to the development of bridge cause in our country. However, how to make good use of this development is of great importance to us, and how to safely construct the bridge to avoid accidents in the construction process is even more important for us. Cable-stayed bridge has been favored by bridge boundary because of its beautiful alignment, strong span ability and other advantages. However, the construction of cable-stayed bridge is very different from other bridges. The construction process of cable-stayed bridge involves not only the construction of main beam, but also the installation of cable-stayed cable, so the construction safety of cable-stayed bridge is getting more and more popular in the society. The importance of bridge workers. Based on the Zhongxing Street Landscape Bridge of the main canal of the South-to-North Water transfer Project in Xingtai City, this paper studies the measurement method of cable force of inclined cable, especially the calculation method of cable force based on vibration measurement, the construction method and monitoring method of bridge. In the construction of cable-stayed bridge, the construction of main beam, bridge tower and cable is the key point of construction. In construction monitoring, the monitoring scheme can be determined by open loop control, feedback control and adaptive control, and the reasonable construction condition can be determined by inverted disassembly method, forward assembly iteration method, stress-free state method, influence matrix method and so on. In this paper, the establishment process of MIDAS finite element model and the division of construction stage of Zhongxing Street Landscape Bridge are introduced in detail, and the construction methods of main beam and stay cable of Zhongxing Street Landscape Bridge are analyzed. The construction monitoring content, emphasis and method of Zhongxing Street Landscape Bridge are studied and formulated, and the survey data in the process of bridge construction combined with the results of finite element analysis are analyzed, which provides a favorable guarantee for the smooth completion of the bridge.
