經過近半個世紀的發展，全省汽車工業已形成了以東風汽車公司為主體，軍工企業、地方企業為依託，整車產品涵蓋中、重、輕、轎、微、專及汽車零部件配套齊全的產業格局，形成了從十堰、襄樊、隨州到武漢沿漢江沿線和從荊州到黃石沿長江沿線的兩條汽車及零部件集聚帶。This paper analyzes and explores stress strain model and principle of the project of concrete diaphragm wall after concluding other engineers and project practices and describing the seepage and deformation character of the plastic concrete used in the cofferdam of the second stage of the three gorges project. we analyze and forecast the change trend by using mathematics statistics regression, then we get the best regression equation. finished it, we used this way to the cofferdam of the second stage of the three gorges project. it proves that the method which i have introduce in this article is effective for the stability of concrete diaphragm wall and it is also a valid for supervising cofferdam security after using it in many projects
本文在總結前人和其他工程實踐的基礎上，結合三峽二期土石圍堰實例綜合分析塑性混凝土防滲墻的滲透和變形特性，對三峽二期圍堰砼防滲墻的應力應變模型、原理進行了分析、探討，在監測分析資料的基礎上進行數學統計回歸分析，並對變形進行預測，通過對砼防滲墻及堰體的應力應變監測數據進行數學統計回歸分析，得出了最佳回歸方程，並對三峽二期圍堰變形進行預測，達到了對圍堰安全性監測評價的最佳效果。The characters of the steel round the barrage are : very convenient in producing and section, fast in construction and in good quality. so, it has been adopted in many bridge ' s deep water foundation in our country
鋼圍堰這種結構型式，製造及拼裝都很方便，施工速度快，質量好，因此國內多座橋梁的深水基礎相繼採用了這一結構形式。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。This paper presents an optimized computer program to analyze different factors that will affect for energy dissipation and erosion preventation which is especially important in design of cofferdams. the graphic in this paper also show the manner and degree of the effect that caused by these factors
