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。
