Application of the concrete shell weir in reconstruction of two flood destructed dams in zhupan
硬殼壩在洙盤兩座水毀大壩修復中的應用 -
The paper introduces large - scale fem software, algor, by which the auther can build model of hanging box of high pile cap, and simulates accurately three loadcases, which include loadcase behind enclosed concrete, loadcase behind empty water in hanging box, and loadcase behind high pile cap construction. the auther calculates tensor and displacement of hanging box weir when loads exert panels, supports, suspenders, top beams, base beams of hanging box weir. at the same time the auther carrys out th e stability analysis, besides, educes calculational and analytical data, which are tally with construction result in the main
論文介紹大型通用有限元計算軟體algor ，並用軟體建立大遼河特大橋高樁承臺吊箱圍堰的全結構模型，相對準確地模擬灌注封底混凝土后、抽除吊箱內河水后、承臺破冰體施工后等三種受力工況，並用模型進行了應力和變形的計算，計算各工況荷載作用於吊箱全結構箱體板面、內支撐、吊桿、懸吊頂梁、底梁等的應力和變形，並對比吊箱圍堰板面計算變形和施工實測變形，結果是吻合的；對大遼河特大橋高樁承臺輕型吊箱的穩定性進行了計算分析；論文研究工作表明，應用組合有限元方法計算大型施工結構問題具有現實意義。
