其次，利用單墩模型，系統地研究了地震波特性、鉛芯橡膠支座參數、橋梁下部結構特性及場地土特性等對隔震橋梁動力響應的影響，提出了在橋梁隔震中合理使用鉛芯橡膠支座的一些建議。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。The earthquake load of its main pile was reduced by over 80 percent. the second sample is a railway simple - beam bridge. the earthquake load of its main pile was reduced by over 50 percent
實例分析表明：設計的鉛芯橡膠支座具有明顯的減震效果，在連續梁橋中，制動墩的減震率達80以上；簡支梁橋中，減震率達50以上。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。分享友人
