一般情況下，為了保證鋼箱梁的質(zhì)量安全，在建橋時(shí)選擇將橋固定在道路上，使橋梁和道路大化地連接在一起。無(wú)論是橋梁的橋面設(shè)計(jì)、橋跨布置還是橋的支座系統(tǒng)都是連在一起的，通常不能移動(dòng)或分開。但有的橋是可以移動(dòng)、閉合、升起、旋轉(zhuǎn)的，它們是一種獨(dú)特的存在。啟閉式橋梁是一種存在了很久的橋梁形式。建橋時(shí)如果不考慮橋梁與接線工程的價(jià)格問(wèn)題，原本要將橋梁建得很高，那鋼箱梁下面的道路便可以自由通行，但是如果這么做的話，不但使得橋梁的上下接線工程會(huì)變得非常大、造價(jià)昂貴而且還影響城市的美感。因而設(shè)計(jì)師便把橋的高度降低，但這樣橋下便不能自由通行了。啟閉式橋梁合理地解決了這一問(wèn)題架設(shè)啟閉式橋梁就是為了如果有船舶要通航的話就將橋梁的大跨度打開，讓船舶通行，這時(shí)橋梁兩邊的行人、車輛都要等到橋梁閉合后才能通行，終達(dá)到行人、車輛、船舶都能通行的效果世界上較早的啟閉式橋梁是中國(guó)的廣濟(jì)橋，該橋建于南宋乾道七年，是由浮船連接而成的，在全世界享有盛名。鋼箱梁目前已經(jīng)逐漸得到了越來(lái)越普遍的應(yīng)用。廣州梁設(shè)計(jì)深化公司</p><p
