被無視的城市景色線——鋁橋說起橋梁資料，人們的反響便是鋼材。其實，近幾年來一些橋梁開端運用合金鋁板來停止制造?；蛟S有朋友該問了，用合金鋁板做橋梁，合金鋁板的強度夠嗎？
　　When it comes to bridge materials, people's first response is steel. In fact, in recent years, some bridges began to use aluminum alloy plate to stop manufacturing. Perhaps a friend should ask, with alloy aluminum plate as a bridge, alloy aluminum plate strength enough?
　　合金鋁板的強度的確比鋼板略低，但這不影響其用來制造橋梁。非常是天橋，合金鋁板的強度綽綽有余。那么運用合金鋁板來制造天橋有什么優(yōu)勢呢？
　　It is true that the strength of aluminum alloy plate is slightly lower than that of steel plate, but this does not affect its use to make bridges. In particular, the strength of overbridge and aluminum alloy plate is more than enough. So what are the advantages of using aluminum alloy plates to make overpasses?
　　抗腐蝕性能強
　　Strong corrosion resistance
　　鋁板價格，對雨水與道路鹽份、泥漿的腐蝕可疏忽不計，非常是5xxx系合金，因而不但建造完后不用刷油漆，在效勞期間也不需定期維護。
　　The price of aluminum plate is negligible for the corrosion of rain water, road salt and mud, especially the 5xxx alloy. Therefore, it is not only unnecessary to paint after construction, but also unnecessary to maintain regularly during the service period.
　　密度低
　　Low density
　　約為鋼的1/3，合金鋁板的密度約為2.7g/cm3，而鋼的密度卻高達7.8g/cm3。

　　The density of alloy aluminum plate is about 2.7g/cm3, while the density of steel is about 7.8g/cm3.
　　6xxx系合金鋁板的強度性能可與低碳鋼的相當，因而比強度（強度質(zhì)量比）、比剛度（比彈性模量）優(yōu)于越鋼材的。
　　The strength performance of 6xxx alloy aluminum plate is comparable to that of low carbon steel, so its specific strength (strength mass ratio) and specific stiffness (specific modulus of elasticity) are far beyond that of steel.
　　可擠壓性能強
　　Strong extrudability
　　這一點關(guān)于建造橋梁來說很重要，由于其能夠消費設(shè)計師所需求的斷面復雜的空心型材，提升接受負載的才能，而不用停止昂貴的切削加工，還能夠消費變斷面型材。由于大擠壓材的應用與其質(zhì)量的相對較輕，可在工廠預制橋梁，有利于降低制形成本與運輸費用，縮短裝置時間，對交通影響大大減輕。鋁板價格韌性高This is very important for the construction of bridges, because it can consume the complex hollow sections required by designers, increase the ability to accept loads, without stopping expensive cutting, and also can consume variable section sections. Because of the application of large extrusion material and its relatively light quality, the bridge can be prefabricated in the factory, which is conducive to reducing the cost of forming and transportation, shortening the installation time, and greatly reducing the traffic impact. High price toughness of aluminum plate抗疲倦裂紋擴展才能良好，又無低溫脆性。合金鋁板的強度與塑性均隨著溫度的降落而同步上升，可是90%以上的鋼都有低溫脆性，所以合金鋁板是高寒地域造橋的上乘資料。
　　The fatigue crack growth resistance can be very strong without low temperature brittleness. The strength and plasticity of the alloy aluminum plate increase with the drop of temperature, but more than 90% of the steel has low temperature brittleness, so the alloy aluminum plate is the best data for bridge construction in the high cold region.
　　可回收性強
　　Strong recyclability
　　鋁是循環(huán)經(jīng)濟較佳的金屬資料之一，合金鋁板橋梁在運用期間無腐蝕損失，簡直全部回收，同時廢鋁能耗僅相當于原鋁提取能耗的5%，對資源的循環(huán)應用、節(jié)能減排有著重要意義，具有嚴重社會效益。
　　Aluminum is one of the better metal materials for circular economy. Alloy aluminum plate bridges have no corrosion loss during operation and almost all of them are recovered. At the same time, the energy consumption of waste aluminum is only 5% of the energy consumption of raw aluminum extraction, which is of great significance to the circular application of resources, energy conservation and emission reduction, and has serious social benefits.
