style="text-indent:25px">大部分的鋼橋面板均采用閉口加勁肋的截面形式。不過(guò)，由于開(kāi)口截面類型的加勁肋有著施工便利的優(yōu)勢(shì)，在鋼橋面板應(yīng)力較小的部位可以開(kāi)口截面加勁肋。橋面鋪裝結(jié)構(gòu)的整體剛度和荷載橫向分布，通過(guò)垂直于橋軸方向布置的橫向加勁肋（簡(jiǎn)稱橫肋）來(lái)調(diào)節(jié)。對(duì)于箱梁，箱內(nèi)的橫肋一般成沿箱壁的閉合截面，這種形式的橫肋一般稱為橫隔板。隨著大跨徑鋼橋的建設(shè)，對(duì)鋼橋面鋪裝材料的探索研究許多國(guó)家投入了大量的人力和物力。總結(jié)這近兒十年來(lái)鋼橋面鋪裝建設(shè)的正反兩方面的技術(shù)經(jīng)驗(yàn)。</p><p style="text-indent:25px">鋼橋面板在低溫條件以及車輛荷載作用下是應(yīng)該具備良好的抗裂性能：鋼橋面鋪裝極端低溫相對(duì)于普通公路鋪裝更低，因此鋼橋面鋪裝在面對(duì)低溫時(shí)應(yīng)具備良好的耐低溫性能。隨著溫度的不斷降低，瀝青混凝土勁度將不斷增大，其抵抗變形能力也慢慢降低。由于鋼橋面鋪裝上行車荷載的連續(xù)作用，瀝青材料中部分應(yīng)力由于來(lái)不及松弛，應(yīng)力就慢慢累積在材料之中，一旦累積應(yīng)力超過(guò)了材料抗裂強(qiáng)度時(shí)，橋面鋪裝就會(huì)開(kāi)裂而導(dǎo)致鋼橋面鋪裝發(fā)生破壞。一旦橋面鋪裝產(chǎn)生開(kāi)裂破壞，雨水以及腐蝕性物質(zhì)將沿著裂縫深入鋪裝層深處，由此會(huì)導(dǎo)致多種病害的發(fā)生。因此瀝青混凝土必須滿足良好的耐低溫性。箱型梁的用途也是很多的，主要用在建筑橋梁是用的比較多。</p><div
