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(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用。在安全、實用、經(jīng)濟(jì)、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。在工廠加工成可運輸?shù)膯卧驑?gòu)件，直至包裝發(fā)運。深圳好的鋼橋深化報價</p><p
