Deck pavement of built - up bridge may be too thick or thin due to complex reasons , among which a most important one is the design 摘要裝配式橋梁建造時會出現橋面鋪裝厚度過薄或過厚的現象,原因很復雜,但設計是一個重要原因。
Conventional method of designing built - up bridge can only ensure the deck pavement thickness near the ends of beams , without enough regarding of the middle part 裝配式橋梁的常規設計方法一般只能保證支座附近的橋面鋪裝厚度,橋梁的中間部分則無法保證。
A baseline finite element model must be a full three - dimensional model that can reflect the built - up bridge conditions comprehensively and correctly . in addition , it must be a model properly validated by the bridge field tests 斜拉橋基準有限元模型首先應該是能夠全面、正確反映結構真實性態的完整的計算模型,其次,它還應該是經現場試驗驗證了的有限元模型。
