style="text-indent:25px">1966年英國(guó)Severn橋的加勁梁較前采用了扁平流線型鋼箱梁，增強(qiáng)了橋梁抗風(fēng)性能和抗扭剛度，同時(shí)直接利用鋼箱梁的頂面板作為橋面，并在其上鋪裝瀝青混合料作為橋面的鋪裝層。將箱內(nèi)空氣干燥裝置用于鋼箱梁，增強(qiáng)了橋面的抗腐性能。1973年土耳其的博斯普魯斯一橋、1981年英國(guó)翰博爾橋、1988年土耳其的博斯普魯斯二橋也采用了扁平流線型鋼箱梁，其橋面鋪裝同樣采用的是橋面系和瀝青混合料薄層的組合。閉口截面加勁肋具有較大的抗扭剛度和抗彎剛度，對(duì)于大跨徑橋梁的結(jié)構(gòu)形式，這種截面類型相對(duì)較好。</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。箱形梁梁翼緣直接對(duì)焊的方式未考慮節(jié)點(diǎn)區(qū)域翼緣處于復(fù)雜應(yīng)力狀態(tài)。</p><div
