【摘要】：隨著科技的發(fā)展和橋梁技術(shù)的進(jìn)步,人們對橋梁功能的需求更加多樣化,在滿足交通功能的條件下,人們對橋梁的外觀造型與周圍環(huán)境的協(xié)調(diào)越來越重視。因此,國內(nèi)外建造了大量造型優(yōu)美又具有當(dāng)?shù)匚幕厣木坝^廊橋。與普通橋梁相比較,景觀廊橋有很大的二期建筑荷載和人群荷載,因此,景觀廊橋在運(yùn)營期更容易出現(xiàn)變形過大的情況,有必要對景觀廊橋運(yùn)營期的變形性能進(jìn)行研究。論文查閱了大量國內(nèi)外相關(guān)資料,總結(jié)了景觀廊橋的發(fā)展歷程和特點(diǎn),對影響多跨連續(xù)梁景觀廊橋運(yùn)營期變形的因素和計算理論做了詳細(xì)的介紹,以某多跨連續(xù)梁景觀廊橋?yàn)檠芯勘尘?利用有限元軟件建立橋梁數(shù)值模型,分析了混凝土收縮和徐變、溫度和濕度變化、預(yù)應(yīng)力損失和人群荷載對廊橋運(yùn)營期變形性能的影響,結(jié)合運(yùn)營期三年的變形實(shí)測數(shù)據(jù),對廊橋運(yùn)營期的安全性進(jìn)行了分析,同時將連續(xù)梁景觀廊橋與普通連續(xù)梁橋進(jìn)行對比,研究了景觀廊橋變形的特點(diǎn),此外對廊橋二期建筑荷載和材料選取的關(guān)系做了分析。論文的研究成果在某多跨連續(xù)梁景觀廊橋運(yùn)營期的監(jiān)控中得到了應(yīng)用。
[Abstract]:With the development of science and technology and the progress of bridge technology, the demand for bridge function is more diversified. Under the condition of satisfying the traffic function, people pay more and more attention to the coordination between the appearance of bridge and the surrounding environment. Therefore, a large number of beautiful and local cultural landscape bridges have been built at home and abroad. Compared with ordinary bridges, landscape covered bridges have large second stage building loads and crowd loads. Therefore, the deformation of landscape covered bridges is more likely to occur in the operation period, so it is necessary to study the deformation performance of landscape covered bridges during operation period. In this paper, a large number of domestic and foreign related materials are consulted, the development history and characteristics of landscape covered bridges are summarized, and the factors affecting the deformation of multi-span continuous beam landscape covered bridges during operation period and the calculation theory are introduced in detail. Taking a multi-span continuous beam landscape gallery bridge as the research background, the finite element software is used to establish the bridge numerical model. The effects of shrinkage and creep of concrete, temperature and humidity change, prestress loss and crowd load on the deformation performance of the bridge during operation are analyzed. Combined with the measured deformation data of three years in operation, the safety of the bridge during operation is analyzed, and the characteristics of the deformation of the bridge are studied by comparing the continuous beam landscape bridge with the common continuous beam bridge. In addition, the relationship between building load and material selection of the second stage of the bridge is analyzed. The research results of this paper are applied to monitor the operation period of a multi-span continuous beam landscape covered bridge.
