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(jià)上，都有明顯的區(qū)別。從許多國(guó)家實(shí)際應(yīng)用情況來(lái)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(duì)溫度、時(shí)間控制非常嚴(yán)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(jià)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(fèi)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(qiáng)度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價(jià)；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。廣州正規(guī)鋼橋繪圖軟件價(jià)格如何防止鋼橋的腐蝕，延長(zhǎng)大橋的使用壽命，是橋梁建設(shè)中的重要任務(wù)。</p><div

style="text-indent:25px">鋼橋一般用鋼板、型鋼等加工制作而成，加工工序多，工藝復(fù)雜，要求較高的技術(shù)和工廠專業(yè)化生產(chǎn)。為了便于控制和保證鋼橋的質(zhì)量，鋼橋一般采用工廠焊接構(gòu)件，工地現(xiàn)場(chǎng)拼裝（**螺栓連接或工地焊接）。鋼結(jié)構(gòu)設(shè)計(jì)要與架設(shè)方案統(tǒng)籌考慮，應(yīng)以經(jīng)濟(jì)合理、便于加工、方便運(yùn)輸安裝和檢查維護(hù)為準(zhǔn)。鋼橋是**、輕型薄壁結(jié)構(gòu)，截面和自重比混凝土橋小，跨越能力大。同時(shí)，鋼橋的剛度相對(duì)較小，變形和振動(dòng)比混凝土橋大。為了保證車(chē)輛行駛安全和舒適性、避免過(guò)大的變形和振動(dòng)對(duì)鋼橋結(jié)構(gòu)產(chǎn)生不利的影響，鋼橋必須有足夠的整體剛度。規(guī)范規(guī)定，由汽車(chē)荷載所引起的豎向撓，不應(yīng)超過(guò)一定的容許值。</p><p style="text-indent:25px">鋼橋設(shè)計(jì)的一般要求和原則：必須有足夠的整體剛度、具有必要的橫向剛度、滿足使用階段的受力和工作性能要求，在施工過(guò)程中滿足應(yīng)力和變形的要求、防腐、疲勞設(shè)計(jì)、不應(yīng)有未栓合或未焊合的接觸部分、應(yīng)盡可能減少構(gòu)件和零件的種類(lèi)，鋼結(jié)構(gòu)的構(gòu)件計(jì)盡可能標(biāo)準(zhǔn)化，使同型構(gòu)件能互換、鋼橋在安裝或檢修支座時(shí)在結(jié)構(gòu)上應(yīng)預(yù)設(shè)可供頂起用的結(jié)構(gòu)?鋼橋的設(shè)計(jì)方法：容許應(yīng)力設(shè)計(jì)法、半概率極限狀態(tài)設(shè)計(jì)法。結(jié)構(gòu)內(nèi)力計(jì)算原則。結(jié)構(gòu)構(gòu)件的內(nèi)力按彈性受力階段確定。變形按構(gòu)件毛截面計(jì)算，不考慮釘（栓）孔削弱的影響。為簡(jiǎn)化計(jì)算，可將橋跨結(jié)構(gòu)劃分為若干個(gè)平面系統(tǒng)計(jì)算，但應(yīng)考慮各個(gè)平面系統(tǒng)的共同作用和相互影響。平面計(jì)算方法中，可以采用荷載橫向分布系數(shù)考慮橋梁結(jié)構(gòu)空間作用的影響。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。</p><div
