</p><p style="text-indent:25px">鋼橋小知識：鋼橋一般用鋼板、型鋼等加工制作而成，加工工序多，工藝復(fù)雜，要求較高的技術(shù)和工廠專業(yè)化生產(chǎn)。為了便于控制和保證鋼橋的質(zhì)量，鋼橋一般采用工廠焊接構(gòu)件，工地現(xiàn)場拼裝（**螺栓連接或工地焊接）。鋼結(jié)構(gòu)設(shè)計(jì)要與架設(shè)方案統(tǒng)籌考慮，應(yīng)以經(jīng)濟(jì)合理、便于加工、方便運(yùn)輸安裝和檢查維護(hù)為準(zhǔn)。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。同時(shí)，鋼橋的剛度相對較小，變形和振動比混凝土橋大。為了保證車輛行駛安全和舒適性、避免過大的變形和振動對鋼橋結(jié)構(gòu)產(chǎn)生不利的影響，鋼橋必須有足夠的整體剛度。規(guī)范規(guī)定，由汽車荷載所引起的豎向撓度（deflection），不應(yīng)超過一定的容許值。鋼橋便于運(yùn)輸，便于無支架施工。</p><div
