style="text-indent:25px">鋼橋發(fā)展的重要前提和淺見：武漢長江大橋所用的是低碳CT.3號鋼；到了南京大橋使用了鞍鋼開發(fā)的16錳“爭氣鋼”，以后也用在枝城長江大橋上；九江長江大橋采用屈服強度420MPa的16vMnVNq鋼,栓焊連接。而在較近建成的武漢天興洲長江大橋和南京大勝關(guān)長江大橋上，主桁桿件采用420鋼，在橋面結(jié)構(gòu)則采用Q370E鋼的鋼板。如今雖然鋼材產(chǎn)量已達飽和狀態(tài)，但在鋼橋的發(fā)展上，對橋梁的耐久性、安全性、全壽命經(jīng)濟性、降低維修費用等方面的要求也與日俱增，相對于砼橋梁的經(jīng)濟競爭力也在不斷增加，而為要取得競爭上的優(yōu)勢，其前提首先要在材質(zhì)上更進一步創(chuàng)新突破，同時在涂裝上宜采用長效防護體系來降低維修頻率，也就隨之降低大量維修費用。在安全、實用、經(jīng)濟、美觀、耐久、環(huán)保六項原則上挖掘潛力，來提高鋼橋發(fā)展的潛在競爭能力是存在有利的優(yōu)勢條件的。</p><p style="text-indent:25px">鋼橋設(shè)計一般要求和原則：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)計要與架設(shè)方案統(tǒng)籌考慮，應(yīng)以經(jīng)濟合理、便于加工、方便運輸安裝和檢查維護為準。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，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。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。</p><div

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**優(yōu)良鋼的冶煉，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)護困難。鋼橋是用鋼材作為主要建造材料的橋梁。具有強度高，剛度大的特點，相對于混凝土橋可減小梁高和自重。由于鋼材的各向同性，質(zhì)地均勻及彈性模量大，使橋的工作情況與計算圖示假定比較符合，另外鋼橋一般采用工廠預(yù)制，工地拼接，施工周期短，加工方便且不受季節(jié)影響。但鋼橋的耐火性，耐腐蝕性差，需要經(jīng)常檢查，維修，養(yǎng)護費用高。正規(guī)鋼橋深化設(shè)計價格</p><p
