style="text-indent:25px">鋼橋設計一般要求和原則：由于未栓合或未焊合的接觸部分的層間緊密度不能保證，容易形成細縫吸水，不易干燥，為了防止鋼梁銹蝕，鋼梁結構中不應有未栓合或未焊合的接觸部分。鋼梁構件上的小坑和凹槽容易引起積水，應該避免。同時，對于箱形結構或有可能積水的部位，應該開泄水孔等，防止由于空氣結露、漏水等原因導致積水。對于開口截面形式，應盡可能避免容易積水和灰塵堆積的構造細節(jié)。鋼橋設計一般要求和原則：為了提高鋼橋制作與安裝的工作效率，應盡可能減少構件和零件的種類，鋼結構的構件設計盡可能標準化，使同型構件能互換，上海正規(guī)鋼橋深化設計軟件企業(yè)。鋼橋構件單元的尺寸和重量大小，應該充分考慮工廠到橋址的運輸條件，上海正規(guī)鋼橋深化設計軟件企業(yè)、運輸能力和吊裝能力。如采用陸路運輸時，上海正規(guī)鋼橋深化設計軟件企業(yè)，構件寬度和長度不能超過車輛和道路可能運輸?shù)妮^大尺寸。同時應該盡可能減少工地組裝或安裝的工作量，減少工地連接，加快施工速度和提高結構質量。如采用水路運輸和大型浮吊吊裝時，可以采用大型節(jié)段，甚至整孔吊裝。橋梁設計的基本原則是安全可靠、適用耐久、經(jīng)濟合理、技術優(yōu)先、環(huán)境保護和可持續(xù)發(fā)展。上海正規(guī)鋼橋深化設計軟件企業(yè)</p><div
