style="text-indent:25px">鋼橋設(shè)計(jì)一般要求和原則：在恒載作用下，橋梁結(jié)構(gòu)會(huì)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(shè)計(jì)線形一致，當(dāng)恒載撓度較大時(shí)，橋跨結(jié)構(gòu)應(yīng)設(shè)預(yù)拱度（Camber）。公路鋼橋規(guī)范規(guī)定，當(dāng)結(jié)構(gòu)重力和靜活載產(chǎn)生的豎向撓度超過跨徑的1/1600時(shí)，應(yīng)設(shè)預(yù)拱度，其值等于結(jié)構(gòu)重力與1/2靜活載產(chǎn)生的豎向撓度之和，起拱應(yīng)做成平順曲線。如橋面在豎曲線上，預(yù)拱度應(yīng)與豎曲線縱坡一致。對于鋼橋采用工地焊接時(shí)，還必須考慮由于焊接產(chǎn)生的結(jié)構(gòu)變形。特別是當(dāng)鋼橋面板采用焊接，鋼梁底板和腹板采用螺栓連接的混和連接結(jié)構(gòu)形式橋梁，在支架上無應(yīng)力狀態(tài)連接時(shí)，焊接產(chǎn)生的變形較大，甚至接近或超過恒載撓度。廣州好的鋼橋深化公司哪家好鋼橋制作需完成的任務(wù)就是，以鋼板和型鋼為主要原材料，按鋼橋成橋要求。</p><div

style="text-indent:25px">纜索懸吊法懸索橋的施工,通常是先架設(shè)纜索,用纜索上臨時(shí)加設(shè)的走行吊架，將加勁梁的梁段逐漸提升，懸掛在纜索垂下的吊桿上，調(diào)整位置后拼裝成整跨的加勁梁。施工時(shí)加勁梁梁段的自重，由纜索承受。美國的金門、韋拉扎諾海峽及英國的亨伯等不錯(cuò)的懸索橋（見彩圖），均用這種方法施工。瑞典阿斯克勒峽灣(Asker Fjord)鋼管拱橋（1960年）,利用同一原理提升跨度278米的管拱節(jié)段，懸吊在臨時(shí)施工的纜索下，調(diào)整位置后拼鉚成拱，整體降落到支座上。拱、梁組合結(jié)構(gòu)，也可采用此法安裝架設(shè),如日本天草二號(hào)橋（1966年）的156.8米朗格爾桁架梁，就是這樣施工的。</p><p style="text-indent:25px">裝配式鋼橋在世界各地都得到了普遍應(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(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，并開始普遍泛應(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)普遍應(yīng)用于**戰(zhàn)備、交通工程、市政水利工程。當(dāng)恒載撓度較大時(shí)，橋跨結(jié)構(gòu)應(yīng)設(shè)預(yù)拱度（Camber）。</p><div
