style="text-indent:25px">近年來，中國鋼結構橋梁發(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構的優(yōu)勢越來越明顯。橋梁是為滿足交通功能的建筑物，現(xiàn)代橋梁鋼結構由結構鋼加上單元經(jīng)焊（栓）連接組成為復雜的受力系統(tǒng)，有明確的承載安全和服役耐久性要求。鋼結構橋跨度較大，如果再加上橋面寬于鋼梁，活載不是優(yōu)，弄不好橫梁外側支座受力增大，而內(nèi)側支座出現(xiàn)不受力，這樣橫梁受力極其不均勻，發(fā)生梁體的傾覆。在設計過程中，通過合理的計算，來設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">工藝裝備主要有胎型、卡具和鉆孔套樣板。胎型的功能是用其擋具來控制構件的幾何形狀及尺寸，一般由底盤、定位擋具及托架組成，分固定和轉動兩種形式。桁架梁的鉚接縱梁和橫梁,可在**的固定胎型組裝,用沖釘及組裝螺栓固定各料件的相對位置后，扳開擋具將構件吊出胎型，再行鉚合。主桁桿件則可用卡具控制其截面寬度。焊接桁梁構件或箱形梁段，可用卡具或胎型控制其各部尺寸，并用定位焊固定其料件的相對位置后，再移到轉胎內(nèi)施焊（為避免仰焊以保質量）。鉆孔套樣板習稱機器樣板，它是在厚度小為12毫米的鋼板上按照孔眼位置鑲嵌滲碳鋼鉆孔套而成。鉆孔套硬度高于鉆頭，其位置及內(nèi)徑尺寸精度高，用它控制鉆孔，可保證孔眼精度。近年來，數(shù)控技術已逐步應用到鋼橋制造的放樣、焰割、制孔等工序，使鋼橋生產(chǎn)自動化程度和產(chǎn)品質量得到有效提高。鋼橋在工地的安裝速度也快。</p><div

style="text-indent:25px">鋼結構橋梁的優(yōu)點：鋼材的抗拉、抗壓、抗剪強度相對來說較高，鋼構件斷面小、自重輕。鋼材的塑性和韌性好，使鋼結構橋梁的抗震性能好。施工工期短。鋼結構的材料加工簡易而迅速；材料的運輸量少，施工現(xiàn)場占地面積小，連接簡便，安裝方便，施工周期短。鋼結構是環(huán)保產(chǎn)品。舊部件可重新熔煉，可節(jié)約能源，符合可持續(xù)發(fā)展的政策。　　鋼結構橋梁適用范圍廣。鋼混結構適用于500m以下跨度的拱橋和斜拉橋，不適用于懸索橋；鋼結構橋適用于不同跨度的拱橋、懸索橋和斜拉橋，特別是大跨度的懸索橋。鋼橋質量容易保證。鋼結構橋梁適用范圍廣。北京鋼橋結構設計</p><p

style="text-indent:25px">剛柔相濟和重心就是平衡，對鋼橋結構來說是內(nèi)力和外力的平衡。否則整個結構就會失去平衡而倒塌，所以橋梁設計的一原則就是要找到結構內(nèi)力和外力的平衡點，例如連續(xù)梁中跨活載和邊跨反力的平衡，自錨式拱橋水平力的平衡等都是內(nèi)力和外力的平衡，構件截面應力積分就是內(nèi)力等，此乃橋梁設計的一要素。其實社會和許多行業(yè)又何嘗不是平衡呢？只不過是人和人的平衡。這種平衡是動態(tài)的，所以會出現(xiàn)現(xiàn)在東風壓倒西風，明天出現(xiàn)西風壓倒東風。天平就是一個平衡好的例子，一邊是忠臣，一邊是佞臣，天平就這樣時而此邊高，時而彼邊高，但是天平的支點總是在移動，目的就是為了讓天平保持動態(tài)的平衡。如果那天天平的一側太高而失去了平衡，必然導致社會的變革，又會形成一種新的平衡狀態(tài)，社會也是在這種動態(tài)的平衡中發(fā)展。北京鋼橋結構設計</p><p
