style="text-indent:25px">1966年英國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">鋼橋由于一直處于微小變動(dòng)狀態(tài)，良好的橋面鋪裝剛度以及強(qiáng)度是橋面鋪裝應(yīng)該具備的性能。足夠的橋面鋪裝層厚度一般都能保證橋面鋪裝具備足夠的剛度和強(qiáng)度。但是一方面鋼橋面鋪裝應(yīng)該保證有足夠的鋪裝層厚度以確保橋面鋪裝具備足夠的剛度；另一方面如果橋面鋪裝如果太厚了就會(huì)影響橋面鋪裝對(duì)鋼橋面板的變形追從性。因此在保證橋面鋪裝具備足夠剛度的同時(shí)不能使橋面鋪裝層過厚影響其與鋼橋面鋼板的變形追從性。橋面鋪裝粘結(jié)層起著承上啟下的作用，將瀝青混凝上層與鋼橋面板連接起來，使瀝青混凝土與鋼橋面板整體受力。因此粘結(jié)層質(zhì)量的好壞直接影響橋面系整體受力狀態(tài)。箱形梁不利于組合樓板的鋪設(shè)施工。</p><div
