style="text-indent:25px">中國目前發(fā)展鋼橋的機遇和展望：‘十二五’期間，我國的鋼鐵工業(yè)發(fā)展，勢必將由規(guī)模擴張為主向品種、質(zhì)量、效益為主轉(zhuǎn)型。全行業(yè)的運行態(tài)勢由外延擴張向提高運行的質(zhì)量和效益轉(zhuǎn)變。近10年來，我國的鋼橋發(fā)展緊隨鋼材質(zhì)量的提高和制造技術(shù)的進步如火如荼向前推進?？缭介L江、黃河等江河的大跨度鐵路橋梁，都采用了鋼梁結(jié)構(gòu)，如武漢天興洲公鐵兩用長江大橋，為四線鐵路六車道城市道路的橋面雙層結(jié)構(gòu)，上層為公路，下層為鐵路，主橋采用98＋196＋504＋196＋98五跨過江，全長為1092米的雙塔三索斜拉橋。又如南京大勝關(guān)六線鐵路長江大橋是舉世矚目的特大橋，主橋采用108＋192＋336＋192＋108全長1615米，基本覆蓋了全部水域范圍的六跨連續(xù)大跨度鋼桁梁拱橋。還有安徽銅陵公鐵兩用長江大橋、鄭州黃河公鐵兩用大橋、京滬高速鐵路濟南黃河大橋等各座大橋的跨度都較大，設(shè)計時速均在200公里/時以上；而且采用了多項新技術(shù)、新材料、并且均取得了成功，為今后鋼橋的發(fā)展提供了參考的技術(shù)平臺。</p><p style="text-indent:25px">裝配式鋼橋在世界各地都得到了廣泛應(yīng)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(shè)計。主要的設(shè)計概念是以較少種類的單元構(gòu)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(shè)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，并開始廣泛應(yīng)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)廣泛應(yīng)用于**戰(zhàn)備、交通工程、市政水利工程。鋼橋構(gòu)件的工廠加工需要經(jīng)過材料預(yù)處理。</p><div

我國生產(chǎn)的200型系列鋼橋，不僅吸收了"321"鋼橋快速、經(jīng)濟、適應(yīng)面廣、組合結(jié)構(gòu)系統(tǒng)性好、互換性強、容易組裝等優(yōu)點，而且還在強度、剛度、抗疲勞性、穩(wěn)定性和整體性能等方面，都有較大的改進和提高。但"321"鋼橋有它輕巧、靈活、快捷、經(jīng)濟適應(yīng)的突出優(yōu)點，在一些跨徑較小、荷載不大的橋梁中仍在使用。目前國內(nèi)出現(xiàn)了以200型系列鋼橋為主，"321"鋼橋并存的形勢。鋼橋是**、輕型薄壁結(jié)構(gòu)，截面和自重比混凝土橋小，跨越能力大。北京正規(guī)鋼橋深化設(shè)計服務(wù)企業(yè)</p><p

由于鋼材的各向同性，質(zhì)地均勻及彈性模量大，使橋的工作情況與計算圖示假定比較符合，另外鋼橋一般采用工廠預(yù)制，工地拼接，施工周期短，加工方便且不受季節(jié)影響。但鋼橋的耐火性，耐腐蝕性差，需要經(jīng)常檢查，維修，養(yǎng)護費用高。鋼橋自身的主要特點是：1、跨越能力大。2、合適無工業(yè)化制造。3、便于運輸。4、安裝速度快。5、鋼橋構(gòu)件易于修復(fù)和更換。6、鋼材易腐蝕，故鋼橋的養(yǎng)護費用高。北京正規(guī)鋼橋深化設(shè)計服務(wù)企業(yè)</p><p
