style="text-indent:25px">安全是鋼橋結構設計的前提：隨著改變開放的力度加大，城市車輛的飛速發(fā)展，城市交通運輸十分繁忙，車速也在不斷提高，橋梁結構不光要求結構自身的受力安全，而且要求橋梁構造的安全。在作樂山市大渡河龔嘴電站大橋設計中，我們設計組也進行了許多方案比選，有河中設墩的連續(xù)箱梁，有連續(xù)剛構，有上承式拱橋等橋梁結構形式。根據(jù)實際的地形、地質、地物，后綜合比較選擇了中承式拱橋，一跨135米跨過，保證了急流的大渡河流水斷面和橋梁結構自身安全（該橋驗算荷載為特種荷載-300，已于1999年10月通車，并進行了動、靜載實驗，運行良好）。又如在大營坡立交橋設計中，橋墩是采用圓柱還是方柱問題上，我們設計組也進行了結構分析和討論，終一致選擇用方柱，保證橋墩的結構剛度（因上部結構傳下的偏心彎矩較大），方柱的四角采用了R15cm的圓角，以盡量減少橋下車輛對橋墩摩擦引起橋梁結構的不安全和增強橋梁建筑的美觀。上海鋼橋繪圖軟件多少錢建成的橋梁要保證使用年限，并便于檢查和維護。</p><div

style="text-indent:25px">剛構橋，也叫做鋼橋，主要承重結構采用剛構的橋梁，即梁和腿或墩臺身構成剛性連接。剛構橋的主要承重結構是梁與橋墩固結的剛架結構，由于墩梁固結，使得梁和橋墩整體受力，橋墩不僅承受梁上荷載引起的豎向壓力，還承擔彎矩和水平推力。剛構橋在豎向荷載作用下，梁的彎矩通常比同等跨徑連續(xù)梁或簡支梁小，其跨越能力大于梁橋；墩梁固結省去了大型支座，結構整體性強、抗震性能好。因此，預應力混凝土剛構橋是目前大跨徑橋梁的主要橋型</p><p style="text-indent:25px">裝配式鋼橋在世界各地都得到了普遍應用。較初的裝配式鋼橋由英國唐納德·貝雷（Donald Bailey）工程師在1938年第二次世界大戰(zhàn)初期設計。主要的設計概念是以較少種類的單元構件，拼裝成能承載各種荷載、不同跨徑的裝配式鋼橋，且只需一般中型卡車運輸，特殊情況下并能全部以依靠人力來搭建。在第二次世界大戰(zhàn)期間，裝配式鋼橋被大量用于歐洲及遠東戰(zhàn)場，搶修橋梁或架設臨時便橋。美國于1941年從英國購買了**，制造裝配式鋼橋，命名為M1型；經(jīng)過改進后（車行道加寬12%），命名為M2型。二戰(zhàn)后，許多國家引進了裝配式鋼橋，并開始普遍泛應用于民用。在中國，裝配式鋼橋也得到了很大發(fā)展，并于1965年定型生產(chǎn)，現(xiàn)普遍應用于**戰(zhàn)備、交通工程、市政水利工程。不可把美觀片面地理解為豪華的細部裝飾。</p><div

style="text-indent:25px">鋼橋設計一般要求和原則：鋼橋的另一缺點是疲勞。影響鋼橋疲勞的主要因素有：鋼材品質、荷載性質、應力狀態(tài)、連接的構造與方法、構造細節(jié)等。鋼橋的設計必須選用有足夠韌性的鋼材，盡可能避免應力集中和容易出現(xiàn)疲勞的構造細節(jié)、連接構造與方法。結構在其傳力途徑中的截面變化的緩急程度是影響應力集中的主要因素，鋼橋設計中應該避免截面的急劇變化。如T形連接中盡可能設置曲線過渡段，避免出現(xiàn)隅角。鋼橋設計不僅要滿足使用階段的受力和工作性能要求，而且應分析施工吊裝和調整支座等受力狀況，使鋼橋在施工過程中滿足應力和變形的要求?？紤]到吊裝過程中的慣性作用和其他不可預見的不利因素影響，公路鋼橋規(guī)范規(guī)定，鋼橋施工驗算時起頂設備及結構本身都應按起頂重力增加30％驗算。在恒載作用下，橋梁結構會產(chǎn)生變形，為了保證鋼橋成橋后的橋面線形盡可能與線路設計線形一致。北京好的鋼橋軟件價格</p><p

style="text-indent:25px">不同瀝青鋪裝材料用于鋼橋面鋪裝，不僅在性能上而且在施工工藝以及在工程造價上，都有明顯的區(qū)別。從許多國家實際應用情況來看，在使用性能和使用壽命方面，以環(huán)氧瀝青鋪裝較好，澆注式瀝青和SMA次之，普通瀝青較差。在施工工藝方面，環(huán)氧瀝青混合料拌制工藝雖不是太復雜，但對溫度、時間控制非常嚴格；澆注式瀝青工藝比較特別，需要特殊的拌制設備；SMA只是比普通瀝青路面復雜一些。在工程造價方面，如以同樣厚度相比較，則環(huán)氧瀝青鋪裝成本較高，澆注式瀝青鋪裝次之，SMA比普通瀝青費用約增加20%～30%，但比環(huán)氧瀝青和澆注式瀝青為低。然而，環(huán)氧瀝青因強度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復合使用。好的鋼橋設計哪家好</p><p
