The conclusions are list as follows : ( 1 ) the mechanical properties of different parts of the bridge are as follows : arch is under the combined action of compression and bend ; open spandrel beam is under the combined action of tension and bend ; close spandrel beam is under the combined action of compression ( or tension ) and bend, but the axis force is small
本文得出的結論如下： （ 1 ）空腹式剛架拱橋的受力兼具梁和拱的特點。結構各部位的受力特性如下：斜腿為壓彎作用；空腹段梁體為拉彎作用；中跨實腹段梁體為壓彎作用或拉彎作用，但軸向力較小，受力更接近純彎構件。 -

拱橋;屈曲雙腿，提起臀部，放下鍛?大腿，臀部及背部肌肉，注意:由於拱橋運動量比較大，因此做完拱橋后，要休息一下，才做其他運動 -
This paper deploys research about the damnification identify, employ capacity and reinforce technology with reason of double bend arch bridge through finding out disease position of construct and cause, colligating these result of the actual bridge detection and load test and analysis and research on the theoretics of damnification, and so on, despending on a lots of measure and means, finding out its present condition and checking structure internal force through choosing the proper mechanics model according as a lots of prototype information
本題以安徽省省道s310上k139 + 000處的大店崗橋為實例，從檢測入手，利用各種檢測方法和手段，了解雙曲拱橋的現行工況，並依據各類原型資料選擇合適的力學模型進行結構內力驗算，通過荷載試驗、理論分析等方法，查明結構的病害部位和形成原因，綜合實橋檢測結果和荷載試驗結果以及損傷理論的分析研究等等，展開對雙曲拱類橋型的損傷鑒定、使用能力和合理加固技術方法的研究。 -
In this paper, using large - scale current finite element software, analysising nanbu jialingjiang bridge as engineering example, considering the united action of arcade and of arch with the structure on crown, the author build several 3d finite element models including original bridge, dangerous bridge, all phases of strengthening bridges and strengthened bridge. in order to decide the most unfavorable load case accurately and quickly, using static analysis method this paper draws out the influence surface of bend moment for main section ; base on built models the paper analyzes the internal forces on entirely strengthening process and knows the damaged degree of dangerous bridge and does feasibility studying on its strengthening method ; finally, the paper simply analyzes the unite action of arcade and of arch with the structure on crown
本文利用大型通用有限元軟體，結合南部嘉陵江大橋這一具體的工程實例，考慮連拱及拱與拱上建築的聯合作用，建立了包括原橋、危橋、加固各階段和加固后各狀態在內的空間計算模型；為了準確、快捷的確定最不利荷載工況，利用靜力法繪制了舊橋主拱圈各控制截面的彎矩影響面；對其加固改造全過程進行了靜力分析計算，明確了危橋的病害程度並對其加固方法進行了可行性研究；最後，簡單分析了考慮連拱及拱上建築與否對該橋主拱圈內力的影響。
