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。( 2 ) validate whether the crest elevation can meet the require of energy dissipation and erosion prevention during the beginning period of flood discharge. ( 3 ) calculate the altitude of downriver cofferdam, and make it meet the require of energy dissipation and erosion prevention. ( 4 ) calculate some average velocity of flow through some sections, including contracted section in stilling basins behind upriver cofferdam, if the hydraulic jump happen in lower reaches of the river. the program will calculate the average velocity of flow of contracted section and the length of the apron
主要設計內容包括：計算上游圍堰后消力池的尺寸；驗證泄洪初期壩面高程是否能夠滿足消能防沖需要；計算下游圍堰堰頂高程，使其滿足泄洪期圍堰和壩體過流的消能防沖和工程進度的需要；計算部分斷面平均流速，包括：上游圍堰后消力池中收縮斷面的斷面平均流速；壩首和壩末的斷面平均流速；當下遊河道發生水躍時，計算下遊河道的收縮斷面平均流速及需要鋪設護坦的長度。In this paper a date from some real projects are used to analyse the facors that will affect the energy dissipation and erosion prevention. such as flood discharge across the cofferdam, crest elevation, downriver cofferdam, roughness coefficient and the gradient of the surface of dam, and so on. in this paper, the program based on hydraulics is checkout by the tankeng waterpower project in zhejiang. the results prove that this program can be used to design any project where there is no obvious side shrinking phenomena
本文結合工程實際對影響圍堰和壩體消能防沖的各種因素，包括過堰流量、壩面高程、下游圍堰堰頂高程、壩面糙率、壩面坡度等進行了分析，並藉助水力學知識和計算機語言編寫了圍堰和壩體的優化計算程序，並利用浙江灘坑水電站工程對所提出優化計算程序進行了驗證，證明了該程序在沒有明顯的側收縮的影響下，計算結果與實際情況較為吻合。Methods of measurement of liquid flow in open channels - weirs and flumes - v - shaped broad crested weirs
