跨間橋墩
英文
standing pier-
Each bridge is a two girder continuous structure extending over three spans with small haunches at the interior piers.
每一座橋是雙主梁的連接梁，延伸三跨，在中間橋墩處具有小的加腋承托。The clear span of a bridge is the gap from the near edge of the next.
橋梁的凈跨，是自一個橋墩的近側邊到相鄰橋墩近側邊之間的間距。Concrete elastic modulus and concrete creep and shrinkage variety at different time are reckoned in by using time increment analysis method and concrete creep and shrinkage secondary force is calculated by using effective elastic modulus. bridge stability analysis program is developed on the base of structure matrix displacement method, the program adopts visual basic language, has friendly interface and visual data input windows. the buckling safety factor of currently finished structure is given as result
為計入混凝土彈性模量的變化及混凝土徐變收縮隨混凝土的齡期與外荷載加載時間不同而變化的影響，採用時間增量法對每個計算階段根據其階段內時步數進行循環，以計算時段內彈性應力、應變增量和徐變、收縮產生的應力應變增量，利用有效彈性模量法計算混凝土徐變收縮次內力，在此基礎上，結合結構矩陣位移法的基本理論編制開發了計入混凝土時效效應的高墩大跨徑橋梁穩定分析程序。Taking the long span continuous rigid - frame structure of the south bank approach spans of wuhan tianxingzhou changjiang river bridge as the research object, and using the large scale finite element analysis program ansys and two ways of modeling with solid element and spatial beam element, this paper respectively analyzes the dynamic characteristics of the rigid - frame structure of the approach spans, makes a study of the influences of rigidity changes and bearings failure of the thin - wall piers on the dynamic characteristics of the structure of the approach spans and also compares the results of numerical analysis of the two kinds of modeling
摘要以武漢天興洲長江大橋南岸引橋大跨度連續剛構為研究對象，運用大型有限元分析程序ansys ，採用實體模型與空間梁單元兩種建模方式，分別分析了其動力特性，探討了薄壁墩的剛度變化與支座失效對其動力性能的影響，並對兩種模型的數值分析結果進行了比較。Spatial geometrical nonlinear analysis of large - span bridge with high - pier
高墩大跨橋梁空間幾何非線性分析Next, a three - span curve continuous box beam has been studied by fem, and how to set the single - pedestal pier in curve continuous box beams has been discussed. when setting the single - pedestal pier, the vehicle flow should be inspected firstly, and then a best offset distance should be selected within the feasible range of the offset distance. meanwhile, increase the spacing interval of the double supports to the largest extent when installing a double supports on a sharing single - pedestal pier, which can enhance the stability and security of the bridge as a whole
對上石立交橋中一座三跨連續的曲線箱梁進行有限元分析，詳細地討論了在曲線箱梁中如何合理設置獨柱墩的問題，分析表明獨柱墩的設置應該根據車流調查的實際情況，再結合結構本身的特徵，在可行的偏距范圍內選擇一個最佳的偏距，另在對公共墩上的雙支座進行設置的時候應該盡量使雙支座的間距增大，這樣可以保證橋梁整體的穩定性和安全性。According to construction features of three - span prestressed concrete and continuous rigid frame box with v pier bridge, the paper demonstrates the shell finite element theories, c onstruct the spatial model, and researches its spatial stress and variable regularity under different loads including uniform load, concentrated load and prestressing force wire. morever, the paper studies vibratory modal of three - span prestressed concrete and continuous rigid frame box with v pier bridge, and sets about experimental investigation of the corresponding practical bridge
本文根據典型的三跨預應力混凝土墩連續剛構橋的特點，提出採用板殼有限元法計算理論，建立其空間分析模型，研究該橋在不同荷載（均布恆載、集中活載、預應力束）支承條件下的空間受力特性和變化規律：探討了典型三跨預應力混凝土墩連續剛構橋的空間靜動力特性及相應的振動模態；探索一般的平面理論預測值與實際空間效應的差異，並進行相應的試驗研究。分享友人
