Bailey）工程師在1938年第二次世界大戰(zhàn)初期設(shè)計(jì)。主要的設(shè)計(jì)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(yùn)輸，特殊情況下并能全部以依靠人力來(lái)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(yuǎn)東戰(zhàn)場(chǎng)，搶修橋梁或架設(shè)臨時(shí)便橋。美國(guó)于1941年從英國(guó)購(gòu)買了**，制造裝配式鋼橋，命名為M1型；經(jīng)過(guò)改進(jìn)后（車行道加寬12%），命名為M2型。二戰(zhàn)后，許多國(guó)家引進(jìn)了裝配式鋼橋，并開始普遍泛應(yīng)用于民用。在中國(guó)，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(yīng)用于**戰(zhàn)備、交通工程、市政水利工程。</p><p style="text-indent:25px">橋梁設(shè)計(jì)基本原則及要求：1．設(shè)計(jì)的要求：橋梁設(shè)計(jì)必須積極采用新結(jié)構(gòu)、新毆備、新材料、新工藝和新的設(shè)計(jì)思想，認(rèn)真研究國(guó)外的優(yōu)先技術(shù)，充分利用國(guó)際較新科學(xué)技術(shù)成果，把國(guó)外的優(yōu)先技術(shù)與我們自己的獨(dú)自創(chuàng)立結(jié)合起來(lái)。保證整個(gè)橋梁結(jié)構(gòu)及其各部分構(gòu)什在制造、運(yùn)輸、安裝和使用過(guò)程中應(yīng)具有足夠的強(qiáng)度、剛度、穩(wěn)定性和耐久性。2．施工的要求。橋梁結(jié)構(gòu)應(yīng)便于制造和安裝，盡量采用優(yōu)先的丁—藝技術(shù)和施：機(jī)械，以利于加快施工速度，保證工程質(zhì)量和施工安全。3．美觀上的要求。在滿足上述要求的前提下，盡可能使橋梁具有優(yōu)美的建筑外型，并與周圍的景物相協(xié)調(diào)。在城市和游覽地區(qū)，應(yīng)史多地考慮橋梁的建筑藝術(shù)，但不可把美觀片面地理解為豪華的細(xì)部裝飾。鋼橋安裝是將工廠制作的構(gòu)件或單元，吊裝就位，連接成橋。</p><div

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(jià)上，都有明顯的區(qū)別。從許多國(guó)家實(shí)際應(yīng)用情況來(lái)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(fù)雜，但對(duì)溫度、時(shí)間控制非常嚴(yán)格；澆注式瀝青工藝比較特別，需要特殊的拌制設(shè)備；SMA只是比普通瀝青路面復(fù)雜一些。在工程造價(jià)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(fèi)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(qiáng)度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價(jià)；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復(fù)合使用。北京鋼橋設(shè)計(jì)軟件公司</p><p
