style="text-indent:25px">鋼橋小知識：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**質(zhì)量鋼的冶煉，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。</p><p style="text-indent:25px">在承認(rèn)施工存在問題的同時，也不可否認(rèn)，在鋼橋設(shè)計領(lǐng)域，特別是關(guān)于鋼橋施工和使用期安全性的問題還有許多可以改進(jìn)的地方。結(jié)構(gòu)設(shè)計的首要任務(wù)是選擇經(jīng)濟(jì)合理的結(jié)構(gòu)方案，其次是結(jié)構(gòu)分析與構(gòu)件和連接的設(shè)計，并取用規(guī)范規(guī)定的安全系數(shù)或可靠性指標(biāo)以保證結(jié)構(gòu)的安全性。不同的環(huán)境和使用條件、不同的設(shè)計對象都會對結(jié)構(gòu)體系提出不同的布局和構(gòu)造等方面的要求。規(guī)范再詳細(xì)也不能包羅本應(yīng)由設(shè)計人員解決的各種問題、規(guī)范更新得再快也適應(yīng)不了新認(rèn)識、新技術(shù)、新材料快速發(fā)展對結(jié)構(gòu)提出的各種新的要求。因此，合理可靠的結(jié)構(gòu)設(shè)計除了滿足規(guī)范的要求外，還要求設(shè)計人員具有對結(jié)構(gòu)本性的正確認(rèn)識、豐富的經(jīng)驗和準(zhǔn)確的判斷。鋼橋的防腐：對于漆膜的綜合耐久性能，還必須考慮到施工條件、維護(hù)管理和經(jīng)濟(jì)等因素。</p><div

style="text-indent:25px">鋼結(jié)構(gòu)橋的防腐：環(huán)氧富鋅涂層作為鋼橋面的防腐蝕涂層，其優(yōu)點(diǎn)是：結(jié)合強(qiáng)度比前兩種方案高，浙江桃夭門大橋鋼橋面防腐蝕涂層結(jié)合強(qiáng)度的檢測結(jié)果為8MPa～12MPa；涂裝后的養(yǎng)護(hù)較無機(jī)富鋅涂層簡單；工期相對于前兩種方案短且初期投入低；且與其后續(xù)鋪裝的防水層具有良好的連接性能；耐高溫性能較好；具有較好的柔韌性。缺點(diǎn)為：相同涂層厚度下與其他兩工藝相比，防腐蝕壽命相對較短。我國基礎(chǔ)建設(shè)的加快，帶動了橋梁技術(shù)的長足發(fā)展，在當(dāng)前形勢下，橋梁鋼結(jié)構(gòu)的整體應(yīng)用也十分普遍，主要是在設(shè)計過程中的優(yōu)化，才能確保橋梁鋼結(jié)構(gòu)的整體性、穩(wěn)定性。必須從整體性角度出發(fā)，較全分析橋梁受力情況，加強(qiáng)焊接形式的優(yōu)化設(shè)計，才能保障橋梁鋼結(jié)構(gòu)的整體質(zhì)量。同時為了保證鋼結(jié)構(gòu)橋梁安全使用，不受腐蝕破壞，必須選用性能良好和使用時間長?0年以上）的防腐涂裝系統(tǒng)，同時增加各涂層的厚度，選用高耐腐蝕的涂料。鋼橋的構(gòu)件較適合用工業(yè)化方法來制造。廣州正規(guī)鋼橋繪圖軟件服務(wù)公司</p><p
