style="text-indent:25px">安全是鋼橋結(jié)構(gòu)設(shè)計的前提：隨著改變開放的力度加大，城市車輛的飛速發(fā)展，城市交通運(yùn)輸十分繁忙，車速也在不斷提高，橋梁結(jié)構(gòu)不光要求結(jié)構(gòu)自身的受力安全，而且要求橋梁構(gòu)造的安全。在作樂山市大渡河龔嘴電站大橋設(shè)計中，我們設(shè)計組也進(jìn)行了許多方案比選，有河中設(shè)墩的連續(xù)箱梁，有連續(xù)剛構(gòu)，有上承式拱橋等橋梁結(jié)構(gòu)形式。根據(jù)實(shí)際的地形、地質(zhì)、地物，后綜合比較選擇了中承式拱橋，一跨135米跨過，保證了急流的大渡河流水?dāng)嗝婧蜆蛄航Y(jié)構(gòu)自身安全（該橋驗(yàn)算荷載為特種荷載-300，已于1999年10月通車，并進(jìn)行了動、靜載實(shí)驗(yàn)，運(yùn)行良好）。又如在大營坡立交橋設(shè)計中，橋墩是采用圓柱還是方柱問題上，我們設(shè)計組也進(jìn)行了結(jié)構(gòu)分析和討論，終一致選擇用方柱，保證橋墩的結(jié)構(gòu)剛度（因上部結(jié)構(gòu)傳下的偏心彎矩較大），方柱的四角采用了R15cm的圓角，以盡量減少橋下車輛對橋墩摩擦引起橋梁結(jié)構(gòu)的不安全和增強(qiáng)橋梁建筑的美觀。</p><p style="text-indent:25px">幾種鋼橋面鋪裝的比較：不同瀝青鋪裝材料用于鋼橋面鋪裝，不*在性能上而且在施工工藝以及在工程造價上，都有明顯的區(qū)別。從許多國家實(shí)際應(yīng)用情況來看，在使用性能和使用壽命方面，以環(huán)氧瀝青鋪裝好，澆注式瀝青和SMA 次之，普通瀝青差。在施工工藝方面，環(huán)氧瀝青混合料拌制工藝雖不是太復(fù)雜，但對溫度、時間控制非常嚴(yán)格；澆注式瀝青工藝比較特別，需要特殊的拌制設(shè)備；SMA 只是比普通瀝青路面復(fù)雜一些。在工程造價方面，如以同樣厚度相比較，則環(huán)氧瀝青鋪裝成本高，澆注式瀝青鋪裝次之，SMA 比普通瀝青費(fèi)用約增加20 % ～30 % ，但比環(huán)氧瀝青和澆注式瀝青為低。然而，環(huán)氧瀝青因強(qiáng)度高，鋪裝層因此可以減薄，減輕了自重，又有利于降低造價；澆注式瀝青鋪裝層厚度也較薄，或與普通瀝青鋪裝復(fù)合使用。鋼橋設(shè)計的時候要具有必要的橫向剛度。</p><div style="width:100%;text-align: center;"><img style="max-width:
