style="text-indent:25px">鋼結(jié)構(gòu)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、維護管理和經(jīng)濟等因素。　　常用的橋面防腐涂層體系電弧噴鋅層作為鋼橋面的防腐蝕涂層，其優(yōu)點是：相同涂層厚度的情況下鋼橋面的防腐蝕壽命長，可以根據(jù)防腐蝕要求設(shè)計涂層厚度；其與鋼橋面的結(jié)合力相對較高，結(jié)合強度可達7M P a～8M P

style="text-indent:25px">幾種鋼橋面鋪裝的比較：不同瀝青鋪裝材料用于鋼橋面鋪裝，不僅在性能上而且在施工工藝以及在工程造價上，都有明顯的區(qū)別。從許多國家實際應(yīng)用情況來看，在使用性能和使用壽命方面，以環(huán)氧瀝青鋪裝好，澆注式瀝青和SMA 次之，普通瀝青差。在施工工藝方面，環(huán)氧瀝青混合料拌制工藝雖不是太復(fù)雜，但對溫度、時間控制非常嚴格；澆注式瀝青工藝比較特別，需要特殊的拌制設(shè)備；SMA 只是比普通瀝青路面復(fù)雜一些。在工程造價方面，如以同樣厚度相比較，則環(huán)氧瀝青鋪裝成本高，澆注式瀝青鋪裝次之，SMA 比普通瀝青費用約增加20 % ～30 % ，但比環(huán)氧瀝青和澆注式瀝青為低。然而，環(huán)氧瀝青因強度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復(fù)合使用。廣州鋼橋深化鋼橋設(shè)計的時候要具有必要的橫向剛度。</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">鋼橋與鋼混凝土橋的不同之處：雖然鋼橋的強度大，但它抗腐蝕性較弱，所以不僅要細心選材，還需要經(jīng)常檢查和維修，費用較高。與鋼筋混凝土橋相比，鋼橋能降低自身梁高和減少自身重量=我們熟悉的武漢長江大橋、南京長江大橋、杭州灣大橋都是鋼橋。鋼筋混凝土橋形成于19世紀后半葉，雖然鋼筋混凝土橋出現(xiàn)較晚，但自出現(xiàn)以來不到200年時間就已經(jīng)被普遍建設(shè)，鋼筋混凝土橋的發(fā)展速度之快有目共睹。鋼筋混凝土橋的主要材料——鋼筋混凝土并非從一開始就被作為橋梁的重要建材使用，它初常用于修建水壩、管道和樓板，直至1875年，法國園藝師才主持建成了一座鋼筋混凝土橋，可惜的是該橋早已不存在了。假如需要架建中小型跨度的橋梁，鋼筋混凝土橋是不錯選擇。假如需要架建跨度較大的橋梁，則選擇鋼橋更合適。</p><p style="text-indent:25px">鋼橋小知識：為了提高鋼橋制作與安裝的工作效率，應(yīng)盡可能減少構(gòu)件和零件的種類，鋼結(jié)構(gòu)的構(gòu)件設(shè)計盡可能標準化，使同型構(gòu)件能互換。鋼橋構(gòu)件單元的尺寸和重量大小，應(yīng)該充分考慮工廠到橋址的運輸條件、運輸能力和吊裝能力。如采用陸路運輸時，構(gòu)件寬度和長度不能超過車輛和道路可能運輸?shù)拇蟪叽?。同時應(yīng)該盡可能減少工地組裝或安裝的工作量，減少工地連接，加快施工速度和提高結(jié)構(gòu)質(zhì)量。如采用水路運輸和大型浮吊吊裝時，可以采用大型節(jié)段，甚至整孔吊裝。鋼橋韌性、延性好，可提高抗震性能。</p><div

style="text-indent:25px">美觀是鋼橋設(shè)計必須考慮的一部分：城市鋼橋建筑不僅是交通工程中的重點建筑物，而且也是美化環(huán)境的點綴品，所以設(shè)計必須精心方案比選、精心設(shè)計、精心施工，以期求得在增加投資不多的條件下，取得橋梁美觀的效果。比如在城區(qū)建一座二、三十米跨度的立交橋，不管用鋼還是預(yù)應(yīng)力砼，通常的做法是用一根等截面梁跨越，但由于人們的視覺有錯覺，所以往往把這根梁看成是帶下垂撓度的彎梁，看起來很不舒服，甚至有怕它掉下來的危險。我們在貴陽市中心環(huán)南線朝陽洞路—玉廠路立交橋方案設(shè)計中，有意把梁底線作成反拱線，在橋墩支點處稍微增加一點材料，但給橋下車輛和行人一種安全美的感覺。實際上呈反拱的下弦就等于是一根弧形托梁，這是一種簡單的支承，它融合在梁體內(nèi)，變得看不出，可它能起到美化橋梁的作用。鋼橋的優(yōu)點是施工現(xiàn)場占地面積小。廣州鋼橋深化</p><p
