style="text-indent:25px">鋼橋是一種橋跨結(jié)構(gòu)用鋼材建造的橋梁。1874年美國(guó)在密西西比河上建造了世界上首座大型鋼橋——圣路易斯(St.Louis)鋼拱橋，第二次世界大戰(zhàn)以后，鋼橋科學(xué)技術(shù)在**質(zhì)量鋼的冶煉，焊接技術(shù)的提高，正交異性鋼橋面板和**螺栓的應(yīng)用，以及結(jié)構(gòu)型式的多樣化等方面，有了很大的發(fā)展，促使大跨度鋼橋的普遍采用。由于鋼材強(qiáng)度高，性能優(yōu)越，表觀密度與容許應(yīng)力之比值小，故鋼橋跨越能力較大。鋼橋的構(gòu)件制造較適合工業(yè)化，運(yùn)輸與安裝均較方便，架設(shè)工期較短，破壞后易修復(fù)和更換，但鋼材易銹蝕，養(yǎng)護(hù)困難。</p><p style="text-indent:25px">主梁由每節(jié)3米長(zhǎng)的桁架用銷(xiāo)子連接而成，位于車(chē)行道的兩側(cè)，主梁間用橫梁相連，每格桁架設(shè)置兩根橫梁；橫梁上設(shè)置4組縱梁，中間兩組為無(wú)扣縱梁，外側(cè)兩組為有扣縱梁；縱梁上鋪設(shè)木質(zhì)橋板），橋板兩側(cè)用緣材固定，橋梁兩端設(shè)有端柱。橫梁上可直接鋪U型橋板。主梁通過(guò)端柱支承于橋座（支座）和座板上，橋梁與進(jìn)出路間用橋頭搭板連接，中間為無(wú)扣搭板，兩側(cè)為有扣搭板，搭板上鋪設(shè)橋板、固定緣材。全橋設(shè)有許多連接系構(gòu)件如斜撐、抗風(fēng)拉桿、支撐架、聯(lián)板等，使橋梁形成穩(wěn)定的空間結(jié)構(gòu)。橋梁設(shè)計(jì)的基本原則是安全可靠、適用耐久、經(jīng)濟(jì)合理、技術(shù)優(yōu)先、環(huán)境保護(hù)和可持續(xù)發(fā)展。</p><div
