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，搶修橋梁或架設(shè)臨時(shí)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(jìn)后（車行道加寬12%），命名為M2型。二戰(zhàn)后，許多國家引進(jìn)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。廣州好的鋼橋深化設(shè)計(jì)軟件企業(yè)</p><p
