style="text-indent:25px">鋼橋設計一般要求和原則：鋼橋的較大缺點是容易腐蝕，如果鋼橋的設計和養(yǎng)護不當，深圳鋼橋軟件報價，將嚴重影響鋼橋的耐久性和使用壽命。目前鋼橋采用較多的重防腐油漆涂層的防腐壽命只有10年左右，深圳鋼橋軟件報價，鋼橋在設計使用期內需要多次進行除去浮銹、舊漆和重新涂裝。鋼橋所有有可能腐蝕的部位都必須留有足夠的空間和進入通道，如箱形結構橫隔板需要開孔并且滿足人員通過的較小尺寸要求，保證結構的可維護性。否則必須采取可靠措施，深圳鋼橋軟件報價，如將結構做成完全封閉形式阻止鋼材銹蝕產生的條件等，確保鋼橋結構在設計使用期內不發(fā)生腐蝕，或者腐蝕控制在預定的程度之內。應盡可能避免采用梁高或梁寬很小的箱形截面或不必要的封閉式結構，減小箱內焊接和養(yǎng)護的難度。橋梁設計必須遵照適用、經濟、安全和美觀的基本原則進行，必須考慮下述各項要求。深圳鋼橋軟件報價</p><div

style="text-indent:25px">安全是鋼橋結構設計的前提：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，橋梁結構不光要求結構自身的受力安全，而且要求橋梁構造的安全。在作樂山市大渡河龔嘴電站大橋設計中，我們設計組也進行了許多方案比選，有河中設墩的連續(xù)箱梁，有連續(xù)剛構，有上承式拱橋等橋梁結構形式。根據實際的地形、地質、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斷面和橋梁結構自身安全（該橋驗算荷載為特種荷載-300，已于1999年10月通車，并進行了動、靜載實驗，運行良好）。又如在大營坡立交橋設計中，橋墩是采用圓柱還是方柱問題上，我們設計組也進行了結構分析和討論，終一致選擇用方柱，保證橋墩的結構剛度（因上部結構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構的不安全和增強橋梁建筑的美觀。廣州正規(guī)鋼橋繪圖軟件公司不可把美觀片面地理解為豪華的細部裝飾。</p><div

style="text-indent:25px">經濟是鋼橋結構設計的保證：一座鋼橋建筑設計的再如何漂亮，若它的造價比看上去一般化的橋梁高出許多，這座漂亮的橋梁設計也是失敗的。在樂山市大渡河龔嘴電站大橋設計中，定下采用中承式拱橋后，拱圈是用鋼筋砼呢，還是鋼管砼？經過比選，我們設計組采用了變截面鋼筋砼拱圈。因為本橋地處偏遠大山之中的大渡河上，當地的砂、石料比較豐富，可就地取材，而鋼管拱不僅昂貴，且鋼管運距也相當遠。故在橋梁設計中，在滿足結構安全的前提下，應盡量地考慮經濟。</p><p style="text-indent:25px">鋼構橋編輯鋼構橋（steel bridge），主要承重結構采用鋼材的橋梁，即鋼結構橋梁、鋼橋。裝配式鋼橋在世界各地都得到了普遍應用。較初的裝配式鋼橋由英國唐納德·貝雷（Donald Bailey）工程師在1938年第二次世界大戰(zhàn)初期設計。主要的設計概念是以較少種類的單元構件，拼裝成能承載各種荷載、不同跨徑的裝配式鋼橋，且只需一般中型卡車運輸，特殊情況下能全部依靠人力來搭建。剛構橋編輯剛構橋（rigid frame bridge），主要承重結構采用剛構的橋梁。梁和腿或墩（臺）身構成剛性連接。結構形式可分為門式剛構橋、斜腿剛構橋、T形剛構橋和連續(xù)剛構橋。鋼橋一般用鋼板、型鋼等加工制作而成，加工工序多，工藝復雜，要求較高的技術和工廠專業(yè)化生產。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">隨著我國水電建設事業(yè)的發(fā)展，大部分江河的水電梯級開發(fā)已延伸到上游，程地點多處于地形復雜、交通不便的山區(qū)，為主體工程服務的進場便道也多跨越水流湍急的江河。在部分船閘改擴建工程中，為了便于通車和提高施工效率，需要在閘首設置臨時道路，連接船閘左右岸，從而延伸施工道路至各施工作業(yè)面。貝雷架橋作為一種具有結構簡單、運輸方便、安拆便捷等特點的裝配式公路鋼橋，經常用于水電站工程的臨時道路工程。我國有3種貝雷橋形式：32l裝配式公路鋼橋、新型戰(zhàn)備公路鋼橋HZCB200型組合鋼橋。321裝配式公路鋼橋仿制原貝雷橋，可以三排雙層架設，車行部寬度為17In;新型戰(zhàn)略公路鋼橋為321裝配式公路鋼橋的改進型，橋面為正交異性鋼橋面，可以四排單層架設，車行部寬度為4ra，還增加外部人行道HZCB200型組合鋼橋桁架片主尺寸與輕便200型一樣，有3種車行部寬度，2種鋼橋面(L型鋼橋面和正交鋼橋面)。韌性、延性好，可提高抗震性能。廣州正規(guī)鋼橋繪圖軟件公司</p><p

style="text-indent:25px">鋼橋設計一般要求和原則：鋼橋的另一缺點是疲勞。影響鋼橋疲勞的主要因素有：鋼材品質、荷載性質、應力狀態(tài)、連接的構造與方法、構造細節(jié)等。鋼橋的設計必須選用有足夠韌性的鋼材，盡可能避免應力集中和容易出現疲勞的構造細節(jié)、連接構造與方法。結構在其傳力途徑中的截面變化的緩急程度是影響應力集中的主要因素，鋼橋設計中應該避免截面的急劇變化。如T形連接中盡可能設置曲線過渡段，避免出現隅角。鋼橋設計不僅要滿足使用階段的受力和工作性能要求，而且應分析施工吊裝和調整支座等受力狀況，使鋼橋在施工過程中滿足應力和變形的要求?？紤]到吊裝過程中的慣性作用和其他不可預見的不利因素影響，公路鋼橋規(guī)范規(guī)定，鋼橋施工驗算時起頂設備及結構本身都應按起頂重力增加30％驗算。深圳鋼橋軟件報價</p><p
