The software ansys6. 0 is used to analysis the stability of the state after construction of tongwamen bridge, linear method is used in analyzing the finite element model of the bridge, the coeffient of stability of different state after construction is given. on the basis, the effect of different factors such as the arrangement of lateral brace, the sloping angle of arch ribs, the stiffness of bridge deck system, the effect of non - orientedly conservative loadings of the hanger and tie bar etc is discussed. the different coefficients of stability of changing these factors are given, so the factors that are vital to the lateral stability of x - type arches are found, and the rationality of the methods taken to enhance the lateral stability of tongwamen bridge is evaluated
本文應用有限元分析商業軟體ansys6 . 0 ，採用線彈性方法，通過對該橋的空間有限元模型進行穩定性分析，得出其成橋運營階段各種工況下的穩定安全系數。在此基礎上，本文還通過有限元模型分析，就拱的矢跨比、吊桿（立柱）的非保向力效應、橋面系的剛度、橫撐布置形式、拱肋側傾角等因素對該橋整體穩定性的影響展開探討與研究。文中給出了各因素變化情況下的穩定安全系數，指出了對鋼管混凝土提籃拱橫向穩定性有顯著影響的因素及其合理變化范圍，並對銅瓦門大橋提高橫向穩定性的措施的經濟合理性進行了分析。A complete ceramic pipe was uncovered to the west of the north ditch, underneath it were large amounts of white ash and brick fragments, the soil was very solid
北側區域排水溝渠西側出現一件頗為完整的陶管，底層遍布大量的白灰與磚瓦碎塊，土質十分硬實。The cfst x - type arches improve the lateral stability by sloping the arc ribs, so it is ofen used in the designs of cfst arch bridge with small ratio of the width to the span. tongwamen bridge is a half - through cfst arch bridge, its span is 238m, and the width of its roadway is 10m, so the truss ribs in - plane is sloped into x - shapc to improve its lateral stability. as the cfst x - type arches with longest span all over the country presently, the design of tongwamen bridge can be used for reference of adopting cfst x - type arches in the design of arch bridges with small ratio of the width to the span
鋼管混凝土x型肋拱橋是一種利用拱肋側傾來提高其橫向整體穩定性的橋型，在寬跨比較小的鋼管混凝土拱橋設計中應用較多。浙江銅瓦門大橋是一座中承式鋼管混凝土無鉸拱橋，跨徑238m ，橋寬10m ，拱肋為平面桁架形式，所以採用了x型拱肋以提高其橫向穩定性。作為國內目前跨徑最大的鋼管混凝土提籃拱橋，該橋的建成對我國今後長大跨徑小寬跨比鋼管混凝土拱橋採用提籃拱具有借鑒意義。On basis of summarizing the characteristics and virtues of the design of tongwamen bridge, the effect of different factors to the cfst x - type arches is given in the end of the paper, its useful for reference to the readers who engage in bridge design
本文在總結銅瓦門大橋設計的特點和優點的基礎上，論述了影響鋼管混凝土提籃拱橋整體穩定性的多種因素，對鋼管混凝土拱橋設計具有一定的參考價值。Standard specification for concrete drain tile metric
