1、武漢科技大學(xué)城市學(xué)院畢業(yè)設(shè)計(jì)（論文）鄂州市方家園橋設(shè)計(jì)摘要斜拉橋，又稱斜張橋，是指一種由一條或多主塔與鋼纜組成來(lái)支撐橋面的橋梁。是由承壓的塔，受拉的索和承彎的梁體組合起來(lái)的一種結(jié)構(gòu)體系。其可看作是拉索代替支墩的多跨彈性支承連續(xù)梁。其可使梁體內(nèi)彎矩減小，降低建筑高度，減輕了結(jié)構(gòu)重量，節(jié)省了材料。斜拉橋由索塔、主梁、斜拉索組成。斜拉橋是我國(guó)大跨徑橋梁最流行的橋型之一。目前為止建成或正在施工的斜拉橋共有30余座，僅次于德國(guó)、日本，而居世界第三位。而大跨徑混凝土斜拉橋的數(shù)量已居世界第一。本設(shè)計(jì)為墩、塔、梁固結(jié)
2、的雙塔雙索面預(yù)應(yīng)力混凝土斜拉橋，選擇橋梁專用軟件Madis可視化結(jié)構(gòu)計(jì)算軟件來(lái)建模分析，先采用剛性支承連續(xù)梁法計(jì)算在自重作用下成橋狀態(tài)斜拉索的受力，從而設(shè)計(jì)出拉索的截面尺寸，斜拉索全部安裝后，一次性整體張拉到位，無(wú)需進(jìn)行索力的二次調(diào)整。進(jìn)而建立整體結(jié)構(gòu)模型，計(jì)算該橋在自重、汽車的作用效應(yīng)。然后進(jìn)行主梁的作用效應(yīng)組合，并估算預(yù)應(yīng)力筋。關(guān)鍵詞：斜拉橋；結(jié)構(gòu)設(shè)計(jì)；主塔；midas59武漢科技大學(xué)城市學(xué)院畢業(yè)設(shè)計(jì)（論文）DesignofEzhouCityhomebridgeAbstractThecable-s
