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(qiáng)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(dá)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(jì)性、降低維修費(fèi)用等方面的要求也與日俱增，相對于砼橋梁的經(jīng)濟(jì)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(jìn)一步創(chuàng)新突破，同時在涂裝上宜采用長效防護(hù)體系來降低維修頻率，也就隨之降低大量維修費(fèi)用。在安全、實(shí)用、經(jīng)濟(jì)、美觀、耐久、環(huán)保六項(xiàng)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">現(xiàn)在，國內(nèi)的結(jié)構(gòu)設(shè)計(jì)過程中，有這樣的傾向：設(shè)計(jì)中考慮強(qiáng)度多而考慮耐久性少；重視強(qiáng)度極限狀態(tài)而不重視使用極限狀態(tài)，而結(jié)構(gòu)在整個生命周期中重要的卻恰恰是使用時的性能表現(xiàn)；重視結(jié)構(gòu)的建造而不重視結(jié)構(gòu)的維護(hù)。實(shí)際上，目前的橋梁設(shè)計(jì)中，對于耐久性更多的只是作為一種概念受到關(guān)注，既沒有明確提出使用年限的要求，也沒有進(jìn)行專門的耐久性設(shè)計(jì)（從材料、結(jié)構(gòu)措施及設(shè)計(jì)程序上上保證耐久性，并明確聲明在何種維護(hù)和使用條件下，橋梁具有哪種程度的耐久性）。這些傾向在一定程度上導(dǎo)致了當(dāng)前工程事件頻發(fā)、結(jié)構(gòu)使用性能差、使用壽命短的不良后果；也與國際結(jié)構(gòu)工程界日益重視耐久性、安全性、適用性的趨勢相違背；也不符合結(jié)構(gòu)動態(tài)和綜合經(jīng)濟(jì)性（考慮結(jié)構(gòu)建設(shè)、使用、維護(hù)等整個周期的費(fèi)用）的要求。充分利用國際較新科學(xué)技術(shù)成果。</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一座大型鋼橋——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**較好鋼的冶煉，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。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)。深圳鋼橋繪圖軟件服務(wù)公司</p><p

style="text-indent:25px">據(jù)我國鋼產(chǎn)量的儲備和材質(zhì)水平不斷提高，尤其是高性能鋼新的品種增多，以及防腐蝕采用電弧噴涂鋅鋁偽合金長效防護(hù)技術(shù)體系，并取得了良好的效果，從而推動鋼橋的發(fā)展提供了有利的條件，同時也就開拓了廣闊發(fā)展的前景。長期以來，一般認(rèn)為鋼橋的造價(jià)要比砼橋梁高得多，但是若在施工工藝上有所創(chuàng)新、配以新材料的應(yīng)用、大型構(gòu)件在工廠預(yù)制、減少現(xiàn)場工序和勞動力需求，則鋼橋的優(yōu)越性就可明顯體現(xiàn)出來。例如杭州錢塘江上的九堡大橋就是一個范例。他們采用頂推的施工方法，將水上施工搬到岸上，鋼構(gòu)件部分基本上在工廠完成，橋面板則采用預(yù)制板，與現(xiàn)場澆筑預(yù)應(yīng)力砼結(jié)構(gòu)相比，其質(zhì)量更有保障，使工程整體在設(shè)計(jì)、施工、維修和管理上更趨合理，因而更具有耐久性，來實(shí)現(xiàn)全壽命的經(jīng)濟(jì)性。該橋主跨85m組合箱梁與同等跨度預(yù)應(yīng)力砼箱梁按每平米綜合工程造價(jià)相比，前者為8497元，后者卻為8815元。這是值得我們的設(shè)計(jì)人員去探索深思的。上海好的鋼橋軟件報(bào)價(jià)</p><p
