style="text-indent:25px">鋼橋小知識(shí)：鋼橋的大缺點(diǎn)是容易腐蝕，如果鋼橋的設(shè)計(jì)和養(yǎng)護(hù)不當(dāng)，將嚴(yán)重影響鋼橋的耐久性和使用壽命。目前鋼橋采用多的重防腐油漆涂層的防腐壽命只有10年左右，鋼橋在設(shè)計(jì)使用期內(nèi)需要多次進(jìn)行除去浮銹、舊漆和重新涂裝。鋼橋所有有可能腐蝕的部位都必須留有足夠的空間和進(jìn)入通道，如箱形結(jié)構(gòu)橫隔板需要開孔并且滿足人員通過的小尺寸要求，保證結(jié)構(gòu)的可維護(hù)性。否則必須采取可靠措施，如將結(jié)構(gòu)做成完全封閉形式阻止鋼材銹蝕產(chǎn)生的條件等，確保鋼橋結(jié)構(gòu)在設(shè)計(jì)使用期內(nèi)不發(fā)生腐蝕，或者腐蝕控制在預(yù)定的程度之內(nèi)。應(yīng)盡可能避免采用梁高或梁寬很小的箱形截面或不必要的封閉式結(jié)構(gòu)，減小箱內(nèi)焊接和養(yǎng)護(hù)的難度。鋼橋的優(yōu)點(diǎn)是鋼結(jié)構(gòu)的材料加工簡(jiǎn)易而迅速。</p><div

style="text-indent:25px">國內(nèi)從上世紀(jì)90年代開始重視了對(duì)結(jié)構(gòu)耐久性的研究，也取得了不少成果。這些研究大多是從材料和統(tǒng)計(jì)分析的角度進(jìn)行的，對(duì)如何從結(jié)構(gòu)和設(shè)計(jì)的角度及如何以設(shè)計(jì)和施工人員易于接受和操作的方式來改善橋梁耐久性卻很少有人研究。而且，長期以來，人們一直偏重于結(jié)構(gòu)計(jì)算方法的研究，卻忽視了對(duì)總體構(gòu)造和細(xì)節(jié)處理方面的關(guān)注。結(jié)構(gòu)的耐久性設(shè)計(jì)與常規(guī)的結(jié)構(gòu)設(shè)計(jì)有著本質(zhì)的區(qū)別，目前需要努力將耐久性的研究從定性分析向定量分析發(fā)展。國外的鋼橋設(shè)計(jì)有鑒于耐久性不足導(dǎo)致的嚴(yán)重?fù)p失，近年來十分重視提高結(jié)構(gòu)物的耐久性并將其作為重要的設(shè)計(jì)原則，統(tǒng)一考慮合理的結(jié)構(gòu)布局和構(gòu)造細(xì)節(jié)，強(qiáng)調(diào)使結(jié)構(gòu)易于檢查、維修，以保證鋼橋的安全使用、盡可能地減少維修費(fèi)用，取得了較好的綜合經(jīng)濟(jì)效益。實(shí)際上，國內(nèi)外的研究和實(shí)踐都表明，結(jié)構(gòu)耐久性對(duì)于橋梁的安全運(yùn)營和經(jīng)濟(jì)性起著決定性作用。鋼結(jié)構(gòu)橋梁適用范圍廣。廣州好的鋼橋設(shè)計(jì)服務(wù)公司</p><p
