style="text-indent:25px">美觀是鋼橋設(shè)計(jì)必須考慮的一部分：城市鋼橋建筑不僅是交通工程中的重點(diǎn)建筑物，而且也是美化環(huán)境的點(diǎn)綴品，所以設(shè)計(jì)必須精心方案比選、精心設(shè)計(jì)、精心施工，以期求得在增加投資不多的條件下，取得橋梁美觀的效果。比如在城區(qū)建一座二、三十米跨度的立交橋，不管用鋼還是預(yù)應(yīng)力砼，通常的做法是用一根等截面梁跨越，但由于人們的視覺有錯(cuò)覺，所以往往把這根梁看成是帶下垂撓度的彎梁，看起來(lái)很不舒服，甚至有怕它掉下來(lái)的危險(xiǎn)。我們?cè)谫F陽(yáng)市中心環(huán)南線朝陽(yáng)洞路—玉廠路立交橋方案設(shè)計(jì)中，有意把梁底線作成反拱線，在橋墩支點(diǎn)處稍微增加一點(diǎn)材料，但給橋下車輛和行人一種安全美的感覺。實(shí)際上呈反拱的下弦就等于是一根弧形托梁，這是一種簡(jiǎn)單的支承，它融合在梁體內(nèi)，變得看不出，可它能起到美化橋梁的作用。采用別的材料來(lái)建橋?qū)⒂龅嚼щy時(shí)，一般采用鋼橋。</p><div
