  1. 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。
  2. The transverse stiffness limitation index ? the permissible ultimate width / span ratio b / l of the continuous steel truss girder of railway bridge is analyzed in accordance with the analytic theories of random vibration of train ? bridge time - variation system and the required derailment coefficients and comfort of drivers and passengers in train running through the bridge. the limitation index in question may be referred to in the design of the continuous steel truss girders of railway bridges

    基於列車-橋梁時變系統隨機振動分析理論，按照橋上列車脫軌安全系數和司機、旅客舒適度的要求，對鐵路連續鋼桁梁橋橫向剛度限值-橋梁容許極限寬跨比b / l進行了分析，對鐵路連續鋼桁梁橋的設計具有一定的參考作用。
  3. The resonance conditions of the train - bridge system are affected by the span, total length, lateral and vertical stiffness of the bridge, the compositions of the train, and the axle arrangements and natural frequencies of the vehicles

    車橋系統的共振條件與橋梁跨度、長度及豎向和橫向剛度，列車編組、車輛軸距參數及車輛的自振頻率等因素有關。
  4. Stability coefficient of large span cfst arch bridge is less than that of considering the geometrical nonlinearity, its numerical value decreases approximate 12 % ; stability coefficient of large span cfst arch bridge taking into account geometrical nonlinearity and material nonlinearity is smallest, and the numerical value is about 45 % of elastic stability coefficient

    拱肋的最大橫向位移為1 . 126米，說明對在該橋型運營實行監控檢測時，可以把雙重非線性分析所得的最大位移作為參考依據。幾何非線性對大跨度鋼管混凝土拱橋的穩定性影響較小。考慮幾何非線性后，穩定系數僅下降了12 。
