style="text-indent:25px">近年來，中國鋼結(jié)構(gòu)橋梁發(fā)展取得了驕人的成績，南京三橋、蘇通大橋、昂船洲大橋的建造，表明在大跨徑橋梁上鋼結(jié)構(gòu)的優(yōu)勢越來越明顯。橋梁是為滿足交通功能的建筑物，現(xiàn)代橋梁鋼結(jié)構(gòu)由結(jié)構(gòu)鋼加上單元經(jīng)焊（栓）連接組成為復(fù)雜的受力系統(tǒng)，有明確的承載安全和服役耐久性要求。鋼結(jié)構(gòu)橋跨度較大，如果再加上橋面寬于鋼梁，活載不是優(yōu)，弄不好橫梁外側(cè)支座受力增大，而內(nèi)側(cè)支座出現(xiàn)不受力，這樣橫梁受力極其不均勻，發(fā)生梁體的傾覆。在設(shè)計過程中，通過合理的計算，來設(shè)計橫梁的偏心受力情況，這樣既可滿足橋梁的荷載要求，也能使得橋體均勻受力。在橫梁處采取灌砂措施，并在滿足規(guī)范的條件下，增加多車道時的橋梁整體穩(wěn)定度。 </p><p 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、靜載實驗，運行良好）。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。鋼橋便于運輸，便于無支架的施工。</p><div

style="text-indent:25px">鋼橋設(shè)計建議:刻意追求美觀，強(qiáng)力硬拽往往會畫蛇添足，適得其反。就拿通常的天橋來說，在山區(qū)或平原區(qū)或城市附近都很有講究，在地形地勢復(fù)雜的山區(qū)道路上，構(gòu)造簡單輕盈的上跨橋便足夠了；而平坦廣闊又有景觀需求的地方往往需要通過上跨橋的造型予以彌補(bǔ)；在城市附近，人車流量大的地方，上跨結(jié)構(gòu)無論是上部結(jié)構(gòu)造型還是下部的構(gòu)造形式都應(yīng)充分重視，甚至橋上的具體裝飾物都應(yīng)無微不至。從根本意義上來說。橋的美觀性應(yīng)該是在平和、自然中又賦予靈動。鋼橋的主要優(yōu)點有受拉、壓、彎、剪均可。上海正規(guī)鋼橋軟件價格</p><p
