鋼橋: (gang qiao)。英文名字叫做：steel bridge </p> <p> 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(jì)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(hù)費(fèi)用高。鋼橋自身的主要特點(diǎn)是：1、跨越能力大。2、合適無工業(yè)化制造。3、便于運(yùn)輸。4、安裝速度快。5、鋼橋構(gòu)件易于修復(fù)和更換。6、鋼材易腐蝕，故鋼橋的養(yǎng)護(hù)費(fèi)用高。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
