The contents include : based on the previous research and the data of experimentations, the author researches and develops a kind of satisfactory semi - empirical formula of nonlinear temperature distribution, and calculates the temperature stress of rigid - framed arch bridge by the fem. the temperature effects of bridge structure by annual and sunlight temperature difference are discussed, it indicates that the temperature effect of annual temperature difference is small but the temperature effect of sunlight temperature difference is great and the temperature stress along beam depth resulted from sunlight temperature difference is nonlinear. with the comparison between the temperature effects of different position of bridge, the results show that where the section of bridge is small, the temperature stress of it is large
本文主要包括以下內容：從理論上研究並結合實測資料發展了一種比較理想的半經驗溫度場非線性分佈公式，並將有限元方法應用於剛架拱橋結構溫度應力的計算中，對橋梁結構進行整體溫度應力分析；討論了年溫差和日照溫差引起的橋梁結構的溫度效應，表明年溫差引起的溫度效應較小，而日照溫差引起的溫度應力較大且沿梁高呈非線性分佈；分析比較了橋梁結構各個部位的溫度效應的大小，可知截面越小溫度拉應力越大，受力越不利；並對箱梁結構由於構造不同引起的縱向與橫向的溫度效應大小進行了探討，發現在頂板下緣也會出現相當大的溫度拉應力，並且梗腋的存在反而增加了頂板底部的溫度拉應力；還對幾種相近的剛構式橋型的溫度效應進行了分析對比，總結了這些橋型針對溫度效應的優劣，並提出相應的針對性措施。 -
Therefore, temperature problem is one of vitally important research topics in structure designing of rigid - framed arch bridge
因此，溫度問題是剛架拱橋乃至橋梁結構設計中的重要研究課題之一。 -
Based on the previous research results, the author takes nonlinear temperature load equivalent to linear temperature load and calculates temperature stress by fem. it analyses the whole and the part temperature effect on rigid - framed arch bridge and compares different thermal stress of different bridge structure by the simplified methods. the research offer advices for this new style bridge
本文在總結前人工作的基礎上，分析探討將非線性溫度荷載等效為線性溫度荷載，同時採用有限元計算溫度應力的簡化方法；並利用這種計算方法對剛架拱橋的整體和局部的溫度效應以及不同橋型溫度效應的不同進行了分析比較，為這種新橋型的工程設計提供參考，還通過實測結果驗證上述方法的正確性，並進行了修正。 -
Rigid - framed arch bridge is a statically indeterminate structure with thrusting force and over the cross section of the bridge structure induce obvious stresses resulted from temperature variations. however, because of the complexity of this bridge structures, it is so difficult to calculate temperature stress, and that researchers and designers have to simplify the calculating methods, and get inaccurate conclusions
剛架拱橋是一種有推力的高次超靜定結構，溫度效應對其的影響相當明顯；但由於其構造復雜，計算結構的溫度應力存在著很大的困難，這就使得研究和設計人員採取簡化的計算方法，但得出的結論粗糙。 -
Also this paper analyzes the effect of different substructure constraint conditions or the size of pier on pier and beam in the light of the use of single - line piles with large diameter, taking into account the mutual effect of pile - earth - structure and the typical mechanic model used. with the analysis result of construction and traffic stages, the suggestion that single - line piles with large diameter claim precedence over all others is submitted in the design of continuous rigid - framed bridge of middle span
對單壁樁柱式橋墩的連續剛構而言，當墩身尺寸改變時，墩身抗推剛度武漢理工大學碩士學位論文亦相應改變，從而對墩身及樁基受力影響顯著，且墩身受力與自身承載能力所要求的橋墩剛度成反比。
